       I've had a short-bed pop-up on several trucks, works fine w/o tailgate. Looking to upgrade to a newer camper, but am only finding 8' longbeds. The tailgate on my 14 Silverado slants up on the back so I would have to build up the bed, not sure there would be much weight (or too much) on tailgate. Also would the TG get road rashed(truck is as new 19K miles). OK to mount without tailgate(would extend 20")??

Center of gravity on these LB' are 30" to 37"(Good) and weights are manageable(pack light, Timbrens Tork Lifts. etc.)

We ran a 7' Palomino on a 6.5' Silverado bed for a couple seasons. We raised the camper, a Dakota model, to clear the cab, and put spacers under the rails to make the bed take most of the load, but resting on the tailgate at the end. We did not get any roadrash on the tailgate, though I suppose you could. Those lightweight popups aren't all that robust in construction, so I really wanted the end supported where I stepped on the threshold to enter the camper. It didn't seem to cause an problems. Just don't overload the tailgate.

Given you can keep horizontal CG close to the rear axle, these are some other issues I see:


1. I doubt a camper without a basement has much support under the floor where it would hang. The camper sidewalls may also buckle at the stress point. If you have to build a platform under the floor to get clearance for the bed rails or cab, that would give you the support you need on the underside.


2. if the camper was made for a long bed, the rear tie down points will be too far to the rear. You will need to add tie down eyelets forward of the truck tail lights so you are not rocking the camper on the rear edge of the truck bed.
