I am looking for general input on that and I had one important thing I was hoping we could all discuss:
What makes a lightweight camper? What should the maximum weight be on a camper considered light weight?
I'm no expert, but IMHO, a lightweight camper could be pegged to half the load capacity of the intended vehicle. For example, if my Tacoma has a load cap of 1500#, the camper (empty) should weigh no more than 750#. Same for trailers...I "can" tow up to 3500#, but my empty trailer weight should be no more than 1750#.
This way my Tacoma has the remaining 750# for people and stuff, but an F350 as a larger truck has a half ton or more excess capacity to go with the extra room the larger truck allows.
A modification of this guideline might be to allow for weight of expected occupants (like 350# for a two-seat truck) before halving the load capacity. That doesn't work so well for the smaller trucks, though. A camper for my Tacoma would max at 575#...simply not practical, IMO. A 60% rule of thumb may work better.
Good idea for discussion...
On edit:
Bear in mind, I drive a 4 cyl truck now, so I tend to be conservative on weights. When I drove a big block chevy, I tended to overload on a regular basis. The truck also did not last, completely my fault. My thoughts these days are biased toward reliability and durability more than in the past, so I drive a Toyota.
The purchaser of the camper will of course have to take into consideration any modifications made to the truck, for better or worse regarding capacity.
