Don't know if you mentioned it above, but how many miles are on the truck, and how long have you owned it? If you really do drive like an old man, and don't subject the truck to much (if any) abuse (hauling, towing, wheeling, etc.) then you can get 150-200K out of a clutch with no problem. I've got a buddy that I've known for a while who's 2wd nissan has 230K miles on it, with the original clutch, his dad bought it new, and drives like an old man. If you drive like an old man, and do a clutch, I wouldn't be surprised if your clutch out lives the truck.
