+1 on the home prep and bag saladsIf I'm truck camping I eat well but do all the prep/cooking at home so I'm just re-heating stuff.
Pasta w/ meat sauce, chicken and rice or potatoes, pulled pork, sausages, steak or pork chops, burgers, etc. Essentially anything you'd eat at home as leftovers makes for great truck camping food. All those are super easy to cook at home, put into quart ziploc bags, then dump into a pan at camp and heat up. Sometimes I'll bring a bag of the pre-mix salad too. For 6 nights I'd probably bring 2 each of 3 different items or even 3 each of 2 different items. I don't worry to much about variety as long as I'm eating a full meal. Throw a loaf of bread in and it's easy to add toast on the side (throw it in a pan w/ butter after you cook your main course).
I try to minimize raw meat in camp just so I don't have to deal with as much cleaning and surface contamination. Eggs are about the only real raw item I bring. Camping is my once/year use of pre-cooked bacon.
Fajitas and taco meat reheat well. There is a southwest style bagged saled thats good to tun into taco salad and you can bring tortillas or chips to eat with it.
Also I really like doing Pre-baked potatoes wrapped in foil. Bake at home so they are pretty much done, then re heat on/in some coals, or have done them on my grill, then just add meat and whatever else you want on top as well (cheese, sour cream, salsa, etc.). Easy one plate meal.
