kenny thomas, I have never owned a v-6 yota, but have owned a Tundra v-8 with a very good experience. I do own a 96 Tacoma with the 2.4,4 cyl, 2wd,5spd. I call it my wheelbarrow, its good for about 600lbs payload. I have got 240k on it, to this day you change oil@ 3k, oil looks like it came out of the bottle when you drain it, uses no oil. I've had no major repairs to drivetrain, just normal stuff. Motor/tranny/rearend stock.
From what I have read on other Toyota sites the only thing V-6 lacks in comparison the the I-4 is MPG, have seen alot of folks talking about mileage well over 200k.
Stocker Steve, I have a delivery service I use, its a 1 man operation and he swears by Chevy's. He has always ran 3/4 ton chevy's. He will run them into the ground. His last one went over 400k, the one he currently drives has some where around 330k. Seems like his biggest issues are the automatic transmissions. He will not carry more than 2k in the bed and does not pull trailers, so its not like the tranny is overloaded.
