I have a 2003 gmc crewcab shortbox duramax. But last month I bought me a 1991 toyota xtracab 4x4 that I drive mostly now. Long trips I take the duramax.
Truck wise I have been a big believer in Toyotas for a long time. I drove an 2003 access cab v8 4x4 from 24k-176k miles, then had to upgrade to my current 2006 double cab to be able to put a baby seat in back. I got it in April with 96k mi and am already up to 111k mi. I do not care for the bigger newer body style on the tundras, that's why I bought the 2006, the last year before they redesigned them.
Gas is a killer, I need to have a buddy for an out of state road trip, coming from the south its about $1000 to get out there and go anywhere. Very manageable for a week if split 2-3 ways, but solo its a nut kick.
I am contemplating on my next move downsized to the newer body style Toyota Tacoma. Only a V6, but I never tow anything other than an atv on a trailer and that's plenty. The newer Toyota Tacomas are about the same body size as the old Tundras, still plenty of room in a double cab. And narrower than most big trucks, so they are more trail capable.
I should have taken a 2 bike trailer on the last trip - we had nowhere to put the elk and looked like a buncha dumb ass red necks from texas on the way back!
