Your a lucky man. You don't mind used....and 7k gives you plenty to choose from. I'd say go gas. Diesel engines are great and all- but everything about them is expensive. Right now I daily drive a 97 crew cab long bed F-350 4x4 with a 351 and a five speed trans. It's got almost 300,000 miles on it. I only gave 3,000 for it three years ago with closer to 250,000 miles. It's super dependable and cheap to fix/maintain. I have a power stroke- but it's not as dependable. Suburbans are awesome, 6.0 chevy 3/4 tons last forever, half tons too, the ford F-250 &5.4 is super solid too. You see what I'm getting at? Pick a flavor that you like and get to looking- there's plenty out there to choose from if your patient and all of them have some great features to build from. Good luck!
