im trying to decide between a 4 and a 6 cylinder x cab tacoma. This will be a daily driver,i live in the mountians, but dont leave town much, i do some offroad trails(rocky mts) and dont plan to haul anything a 4 couldnt handle. my debate is how long a 3.4 v6 would last compared to a 2.7 4 as far as milage goes. ive seen many toyota 4s with 300,000 and still strong, but what about the 6? whats the highest milage 3.4 v6 anyone has seen? thanks in advance to any and all posts.
