Only because you are the only guy I know that is cheaper than I am, and you have a full size truck, so you have the room, get a couple/three of the cheap synthetic fleece type blankets that Food 4 Less (among other high end outdoor gear shops) stocks at the beginning of winter. They are usually $15-20, relatively warm, dry quickly (relative) if they get wet, and mostly, cheap enough to put in front of a tire for traction if stuck in deep sand, use as a ground cloth/tarp when laying under a vehicle, duct taping over a roll cage to form an impromptu roof on a rock crawler, etc... We also use ours as insulation/padding under us when I can't find anything else to use it for, especially when using an air mattress that sucks the heat out of your body.
Even/especially when traveling in my Jeep/tent camping, with limited space, I find room for one somewhere.
