buying a used penthouse for ford e350. Doing the install my self. Found a couple of post on this but not a lot of info. Anyone here done it? If so any advice, pics, videos, measurements etc is appreciated.
How did you measure out where to cut? Did you just lay the frame and center it then draw cut lines?
Start right behind the cross-beam at the cab and just cut the length and width of the rails centered on the van from there. You will have to have the rails and cross bars assembled to get the proper width. I used an air chisel to cut the roof and sawzall to cut the support cross beams.
