I'm thinking of buying one she says its mostly freeway miles. Considering its been taken care of it should be able to get a lot more out of it ATEQ VT55. I'll get it checked out mechanicaly. Aren't v8s on Nissans strong? Should be good for a lot more
Lots of guys are reporting getting 250+ miles some even 300miles. The motor and Tranny on these trucks seem to be bullet proof when taken care of. Check out the thread "refreshing a Gen 1 titan" it will give you a list of known problems to look for when purchasing and basically thing you can expect to go wrong.
I'm currently only at 130k on my truck.
