I full time and have a Davy Crockett. Absolutely love it. Nothing compares to food cooked over a small,smoky wood fire. Ok, not really a fire. I carry a 5 gallon bucket of hickory pellets and one of mesquite in the bed of my truck.
I have the GMG carry bag for mine and just sit it inside the fiver's basement.
There are pros and cons to everything, including packing a pellet grill. But people sure seem to like the ribs I make on it. Or the chicken. Or the pork roast. Life is too short - choose wisely.
I would not remove the legs. Yes, it's a little short - but that's because it's a tailgater model. You basically start these things, then put the food on, then take the food off when it's done. That's 3 opens and closes per meal. Not like cooking on a grill where you check things more often. I'm sure you can find some kind of aluminum pan to set under it as a heat guard if you wanted to set it on a picnic table. But OTOH, these things excel at cooking at lower temps.
