I am joining the ranks of those who do a little truck camping when they fish. I just purchased an '08 Tundra Double Cab and have an ARE Z Series cap on order. I plan on putting it to its initial test on a trip to Colorado in about a month. My question for those of you who camp in their trucks is what do you use for a sleeping solution? Are you using an air mattress, self inflating air pad, foam or something else? I have done a little research and came across the Therma-a-Rest DreamTime and the Paco Pad. They look like nice options, but both are a little pricey. What do you use and are there any forums out there that focus on truck camping?
