The crew at W.W. Williams was fast, friendly, and got our school bus conversion back on the road with zero headache. Prices were fair and parts were fast (lucky).Shout out to Mary in service for making the whole thing super easy. Will definitely be back if we need service again in Vegas!

Daniel Santos was amazing. He kept me well informed throughout the process and got my RV all fixed up. I will definitely be back again!

We are living full time in our motorhome. This is our only shop for service. Their service is awesome, and I feel its a good value for the price. 30 Amp electric if you need it.

I am customer of W W Williams on Phoenix AZ,I thought that by extension they would be awesome as well ... but I got a bit disappointed; I completely understand that from time to time the shop will be overflowing with trucks that need fixing, on those occasions a straightforward answer is the best policy, I dont know if I can see your truck today or something along those lines is deceiving at best, not a good start.A plain I will check your unit tomorrow today we are completely booked is a better answer, that way you know for sure they dont have space for you until next day and you can move on with your life.I did not get to experience the service experience, just because I know the shop in Phoenix I give 2 stars, the fact they were overbooked tells me they might be pretty good service wise but the way they communicate really scares me.

Called W. W. Williams to see if they work on big RVs. I Was told to drop it off at my convenience. I was told that they are very busy and they would get to it when they can. I took a week for mee to clean it out then Dropped it off on a Monday evening. I was told a two hours to diagnose the problem. Wednesday afternoon I got the call it was repaired. I am Happy with my service. They located the problem, fixed it. Road tested it and let me know it was done. I found a new shop for my motorhome. Thank you.

Danny and Merry so wonderful and helpful.They are so great and fast services.They gave great deals for everything for professional

They inspect the whole truck and recommends needed repairs. Honest and concise. Great price and good quality work. I will definitely return.

Definitely like this place. Very kind people. Will visit again

These guys are great!!! Took my truck in on short notice, got everything requested done and fast too! Plus they even fixed an issue i didnt tell them about. Never got billed for it either. Way faster than truck dealerships. And top notch service too!👍👍👍👍👍👍👍👍👍👍👍

DANNY always take good care of us, he keeps us updated of the details and repairs needed, and works with us about getting the trucks back in timely manner. MICHELLE also help us great, great team highly recommend.

Great customer service and repairs were done quickly. They even fixed another issue without even billing me. Definitely will be using them again.

Great service! They are our go to whenever we have a (any, literally) problem with our semi trucks. They fix everything.

Great people to work with. Great service and on time. Would easily come back.

My company has been bringing our fleet trucks to this location for a years! Theres nobody better. When it comes to your fleet, you need details of the progress constantly. The staff here delivers every time!

Never disappointed.One of the best things I like about this place is that, they understand that not only are they a shop but also they are a parts store. What I mean is that they dont keep the instructions torque specs to their parts like some places do.

Folks here seem pretty cool they turned truck back up after replacing computer and cut idle off and changed oil everything works good now

They were reasonably priced and did good work

Very professional and always kept me up to date with everything that needed to be fixed on my truck, I am a resident in vegas I will be going to them from now on.

I love this place if u break downIn vegas I’m going to w.w. Williams

Running great thanks again

Very friendly, great service !

Thanks W W Williams for doing what I asked... more importantly is your technician didnt move my seat, steering wheel etc. to perform the duty of repair. Ill look forward to utilizing your shop for future repairs over my home repair shop. 5 5 5

My husband & I brought our truck to this establishment with high hopes of receiving honest & fair service. We were WRONG!!! This place is a complete joke.We came in because our truck had a regent issue. After being diagnosed we were told it was our D.O.C with the D.P.F. After quoting us our price my husband & I agreed with having our truck fixed. After we made the agreement Danny, the secretary at the front counter, told us we had to pay half of our bill before they could even start working on our truck. 😳 What the hell is that!!! Even the local mechanics will work on your truck without a down payment!! 🤬.Strike One!After being called that our truck was fixed we came to the shop to pick it up. We were assured that everything was fixed. We left there feeling satisfied. Well... so we thought. Three days later we started having the same issue with the regent! Strike TWO!We called W Williams & spoke with Danny. We tried to explain to him that we were experiencing the same issue with our truck. Danny’s response was, “nothing is free”. What in the hell does that mean Danny? We know that “nothing is free”. We paid you $3500 Danny! As a “ professional” you should have asked us to bring our truck back in. Not attempt to remind us that “nothing is free”! Danny is very unprofessional & he does NOT conduct himself as a upstanding W Williams employee. He clearly does not value their customers or his job.Strike THREE & you’re out!!!It was our first time coming here & will be our last!!!As a business owner/ owner operator the truck is our entire livelihood. Without it we don’t have our business. We put our trust & faith in mechanics to just do their job. We uphold our end of the bargain by paying ridiculous prices, without hesitation, why can’t the mechanics at W Williams do the same. The mechanics that we can trust we call them friends.Danny & W Williams are NOT our friend!Be careful my fellow truckers. When you walk into W Williams you will be greeted by that “secretary” at the front counter. I assure you, Danny will be there and he will play “that game”. You all know the one when they act so friendly & helpful. Like they will take care of all your needs without a doubt. Like they care about your truck more than you do. Yes, that’s the one. Danny will sit there acting as though all your problems will be handled on the spot. He will play “ that game” so well you will walk out of there feeling so optimistic & elated that finally you have found a “real” mechanic shop that is honest & fair. Just know it is completely false. He will lie in your face, tell you they fixed all your problems & take your money with a smile.Just be WARNED!F.Y.I... Jimmy was very professional & friendly

Service, quality, is excellent. Very through, great job explaining the work. Will return!

Super knowledgeable. The absolute Detroit people to go see. The People were incredibly Pleasant and fun.

I cant say I would recommend this company and Im a commercial truck dealer. I sent a truck to Williams for engine problems. They sent me an invoice for $1200 for two batteries and an alternator. Heres the funny part, I sent them the truck to rebuild the engine. They told me it ran fine even though I know the #5 Cyl was dead. When my driver went to pick up the truck, without any repairs after almost two weeks, the truck was in the same spot he left it. Cant recommend them.

Motorhome....Engine had a knocking noise they replaced the manifold gaskets, and bolts,, installed fast and great price, got it in the very next day from when I brought it in, 8.9 isl cummins diesel. Great job.

Friendly staff kinda know them for years being regular account customer. Like every other authorized repair dealership theyre not cheap. OEM Detroit and Allison parts dealer

People here are great to work with.I will only let them work on my truck when possible.

Good parts and services

Excellent job very professional I would take every truck that I have there thanks W and W

Took great care of our freightliner it was done when they said it would be and they spotted a couple of potential problems

Service advisors are very nice. 2 different mechanics rode with me to diagnose my problem with the Allison transmission in my Winnebago diesel pusher RV. Theyre doing small steps at a time to try to correct the problem as to keep the cost down which is greatly appreciated and totally honest of them. Transmission is in a learning more now and it has gotten a little better. Need more driving time. Will go back for them to go to the next step if needed. I highly recommend W.W. Williams for all of your needs.

They great! They got my truck back running in a couple of days!

Best place for your Allison transmission...total experts!!

So far so good...asking them to fix what Freightliner did not...

Very good. The tech who worked on our elect short was fast & very knowledgeable. Had paid another business 2 days before $1900 for same problem.

Guys in the shop are great, service guy needs a better attitude or find something that does require him to deal with people.

Dot insp and fix a brakeing light problem

Friendly and fast service by phone, first time ordering parts.Waiting to see how timely they ship and accuracy of my order, will report back.

Stay away from this place, took them two weeks to repair a simple item and they made up a lot of other stuff to repair. For a simple knock sensor they up charged me $6,000 for other repairs that i did not need. Last time Im ever letting a driver take a truck there!

Den of thieves! they tell me the transmission and tow is covered under warranty then in the 19 th hour they tell me nothing was because it was a faulty installed drive line that caused the problem. How would they know it was ? I was there recommended tow company that unhooked and re hooked up the drive line when truck was dropped off. Nice bait and switch Mary! Or shall I say nice try thief!

Great place to make stops along your route of destination.

These guys were awesome. Prices were half that of the dealership and they allowed me to return an unused gasket. Great attitudes and service was quick. They treated me like I was spending thousands. I bought a trans filter and fluid.

I like this people who work there.

Great generator service techs and customer service, also great tech support staff.

Amazing service and helpful people they go above and beyond to help you out

This place used to be good years ago. It seems the good mechanics left and they hired a bunch of new guys who dont know what theyre doing. The last few times I went, the repairs werent done properly but the service advisors were quick to point out other issues that were causing the problems. I got ripped off multiple times. I wont be going in there again.

I went there for intake manifold gasket.They were very helpful . The place is nice and clean I suppose that the service will be outstanding to . Detroit Diesel Forever 🤠

Very quick and professional!!! We did repair on semi truck Freightliner Cascadia, very happy with price and service . Highly recommended!!!!

Had truck work done and very happy with pricing and service. I will be returning, if needed. I was here for my vacation as well and let me leave my truck here for the week. Highly recommend !!

This shop has gone above and beyond to take care of our issues there needs to be more shops like this around! Thanks again Mary in service for setting the bar high for how a service department should handle business!

They have good customer service and knowledgeable mechanics

The parts man was professionall and helped me find a part. Sadly they didnt have it in stockBut he did all he could in locating it

I’m working with this shop in last 11 year and they are great. Thanks a lot and keep up the good work

Replaced my clutch & assembly on 09 387. Broken hood latch and main seal oil leak after job was done. I know for a fact my truck had no leaks and the hood closed perfectly when I dropped it off. Company refused to accept responsibility which left a bad taste in my mouth for these people.

Had 61 code (generic DEF), went to Freightliner, was told a couple of days they can get to me. Called WW Williams, was told couple of hours. They found the harness problem, ordered the part, it shipped the next day. Following morning they got it, and had me out the door 3 hours earlier than they quoted me. I also got my oil changed, filter & line for $149 dollars special. I would HIGHLY recommend going here, especially if you have a Detroit. I meant lube not line.

I wana know is it Detroit dealership?

Way over priced work is shotty at best. Run away if you can.

Dudes were awesome that worked there, and they got me in and out with the new tranny loaded and ready to go.

It was awesome

They are honest, great service and Mary who handles the RVS is a GEM, she checks everything on your bill, Mary called me back and said you do not need a new air filter they could have replaced it as I was in for a service, saved $300.00, Any RV owners our there give them a try.Thank You Mary Jeffrey B

Great service

Nice people but over priced and slow

In and out in less than 6 hrs for what I had done

This is the only place in town to take your truck for repairs!

We had on one of our newer freigliner a injector issue. Towed it to freightliner of las vegas. They told us it would be 2-3 days before they would work on it at all. Ridiculous!!! We decided then to give W.W. Williams a shot. Called them up, explained them the situation. The service rep. Assured me even though they were busy, I still wouldnt wait 2-3 days to start repairs so we took it in. Sure thing, same day fix and all work was covered by warranty.Thank You. Awesomely friendly people.P.S. wish you guys had an burner over for them DPF filters. That way I dont wait another 2 weeks until cummins can get me in like on our other truck with an ISX engine. :-/

W.W. helped me in a way that most shops have forgotten to do, the personal)

Had truck towed to their shop and they did could not fix truck they were just guessing time wise they are the worst customer service its a -1 over all w w Williams is no good.

Bad service! I came for Dot inspection they schedule for 8am and they want me come back at 10am I will never come again to this place. Bad service

They didnt have the part I needed but were helpful nonetheless

Great folks fast and fair

Dont even try !!!!Group of liars..quoted over the phone one price when arrived they tripled the price very slow in organizing .try to avoid them in any price !

Had a RV repaired there for a no start condition for $$$$$ . Two weeks later had the same problem that was repaired at another at another shop.

Dont remember ❓

Good and honest people

Very profetional

Over priced

Great service

I dont like, they dont know how to treat the customer

Special attention, they helped us to solve with the necessary parts for the truck. Thank you
