You definitely still need the structural elements like the closet and the kitchen upper and lower cabinets. The trailer isn't all that useful without the rear benches and table. You could try building them lighter than the originals, but I think it would be difficult to shave a significant amount of
weight off and still be structurally sound. I weighed the original
fiberglass pieces and posted their weights in case anyone decides to try to build something lighter.
Just so there's no confusion:
Only the interior cabinetry was stripped when weighed, so my 400lb empty shell
weight includes doors,
windows, exterior
lights and the wiring required for the exterior
lights. It also has the
propane hoses/pipes/regulator for a
fridge and cooktop. It does not include the frame and drop floor. It does not include exterior fixtures required for shore power and water.
These weights are all done with my '71 Boler's original shell and cabinets. Newer and/or different trailers may be lighter or, more likely, heavier.
