might work...
My brother and I cut down an 80 G10 chevy van to make an enclosed trailer for hauling motorcylcles and swap meet junk--it was nice to just lock the doors and leave the stuff inside until the next trip,rather than have to unload the truck and put it away every time!
It towed well,and we often put a LOT more than we should have in it as far as weight!--we put some coil over shocks on it,and some cheapie air bags a guy was selling at one of the swap meets..but it survived fine without them ....it was the "short" version 110" wheelbase,we made the toungue 5 feet long,to make it back up easier without "jacknifing"--we took the rear brakes out to prevent them from rusting and locking the wheels when stored--a "surge" brake should have been used instead,to assist in stopping with heavy loads--but we towed it with an 82 K30 4x4 with a 454 and a flatbed,so it didnt seem to mind the weight..
5 inch "C" channel fit perfect inside the original uniframe rails,it only took us 2 days to cut the van behind the doors and make the toungue,it was more work closing the front in than the rest of the work involved....we had a lot of guys want to buy it to haul their harleys in...he still has it,its been sitting 6 years now,but I told him I want first dibs on it if he decides to get rid of it,as its a twin to my 81 G10,same blue color!--it would make a nice camper,you can box in the "V" on the tougnue and make a "mens room" or a small kitchen there..its probably starting to get pretty shabby now though..
I dont care much for the utility trailer I made from a 62 GMC 3/4 ton2wd chassis with coil springs--its a bitch to back up due to the short toungue,and it bounces like a basketball-and the control arms were swiss cheese,had to weld angle iron over them so the axle would not drop out!-
-I'm was tempted to put my flatbed/crane setup from my 74 K20 on it,but I'd probably have to make it dead axle or put leaf springs in instead,and I'm not sure how a crane will work on a trailer,it might tip it over fairly easy--more than once I've had a front wheel off the ground on my K20 when hoisting heavy loads in the bed...sounds scary on a trailer--maybe its not a good idea??
