I purchased a new mobile home in 2003. Mason brought it into the park and set it up. He put one half on asphalt and one half on the dirt For years, the home has been separating at the seam...there are large cracks in my bedroom that go across and down the wall...the cracks continue on down the hallway. When I contacted Mason, I was told that was just too bad and they could not fix it. I have had it repaired twice...The place continues to separate. I think they do or did the worse work there is.
