Has anyone here ever used one of those truck tents? I'm headed up to join some friends for a few days of hunting and since they already have a full tent and I'm a recent add-on, I'm thinking about getting a truck tent that I can set up in the bed of my Silverado after offloading the ATV. WalMart advertises one but I hear it isn't all that well built. Cabelas has one of course but it'll never be here by the end of the month. I'll head to SW tomorrow to see if they carry them and it doesn't look like REI has any so, does anyone have another suggestion of where to look?
