I view the DFG Offroad "tire table" as a convenient place to put stuff within reach of a camp stove or "side table" for condiments, a coffee pot, etc. more than an eating table. I have a little folding table for eating, pictured in Post #69.
I haven't received mine yet so I reserve judgment. I'm going to experiment with it and will report back. I have a tailgate table in my jeep that works well as a prep table and to hold a single burner butane stove. A tire table isn't really necessary but might be a nice accessory table. However, my Xterra has a lift hatch and no place to put anything if packed with gear so I can foresee much more use. We will see.
