I have a built in tool box that is level with my rear seats when they are folded down creating a flat surface to sleep on. Is there a Thermarest-type sleeping pad that will cover an area ~55" wide X 75" long? I do not want a regular air mattress that is eight or nine inches thick; there is not that much height available. With something that thick it would be difficult to move around inside the truck. I have found Down Mats from Outdoor Research which are the right idea, but I need to get two of those to cover the whole sleeping area, and I really want one pad that covers the whole space for my wife and I. The Thermarest Dreamtime is also the right type of pad, but they only come single - no doubleish sizes that I can find. I appreciate your input.
