I have a short bed Lance 845 on a long bed Chevy and it works just fine. I built a plywood box to fit in the space, where we store the lawn chairs, any fire wood, tool box, extra water hose, 30 amp extension cord, axe, oils, filters, cleaners, etc. The handling is no difference as the center of gravity on the TC is the same whether on my previous short bed Dodge or the current long bed. The difference in bed length is in front of the rear wheels. Long beds have a longer wheel base. The rear axle is the same basic distance in from the rear of the bed.
We used it this summer for just over two months on the road to the mountain west and put about 6,500 miles on it. I am considering checking with some of the boat fiberglass fabrication shops in this area to see what they would charge to make me a more permanent box of some sort.
If I had it to do again, I would have the box come out over the bed rails on each side. Anything that I put on the floor in the box is not easy to get out, so my 12 volt air compressor, pair of bottle jacks, and other items I seldom have to use go down there. A extra 20 ft sewer hose (new) goes in the box as well. I have the doors on with 4 wing nuts on dowel screws. I have a set of hinges but haven't installed them yet and may not.
