Simply put, get off the ground. I've used an inflatable lounging float, and they suck...too slick! The Coleman air matresses are too heavy for what your wanting, but really nice for the back end of a pickup. I have a Ridgerest and a Thermarest (3/4 length) and would only ever carry the Ridgerest. The Thermarest was free when I purchased my bag several years ago. It too is nice for camping out near the truck, but I wouldn't dare take it on a backpack hunt. I think you will find the Ridgerest will suit you well.
