Good flatbed conversion mr. friend
I'm planning that(nearly) exact conversion, except I plan to possibly use a FE and flat-nose skoolie since I like their reduced turning radius. Very good job there I'll add. I had done pretty similar job with my Isuzu FTR 4door w/26' box. I wanted as low as possible finished height since I was pulling 2travel Trlrs like cadillackid's previous posting for Haul&Tow. It was 34" tall X 27' long, including 4' beaver tail X 102" wide. Since selling it 2yrs ago I always wanted to convert a skoolie into same since parts are (likely) easy to get and my engine&trans choices means mechanics are easier to find. Concerning your sleeper skin I'd advise whatever thin panel u can get locally. I'm in Elkhart(RV Central) so fiberglass, laminates& RV panels are at every RV surplus. Have u gotten done enough to weigh your rig yet?
