I have one of these GM Davy Crockett jobs, it is small but large enough for a couple of racks of ribs or a small briskit and a small turkey, not a lot of wasted space that I never use on a big one. The WiFi works very well. It's legs will fold up so it can be used on the tailgate of your truck and connect up to the truck battery or an auxiliary 12 V battery pack (battery,light, compressor, boost starter)" I have a Stanley one that I keep in the UTV or pickup.
