Been looking around for a new truck, i need it mostly for work and hauling the rv i'm going to buy, about a 20-25' one. Whats a good year to buy a tundra, why are they more expensive then other trucks at least in canada? also been looking at the the new dodge 1500 diesel, but i never owned a diesel before and buying brand new seems like a big money burn something i dont have alot of, or the 1500 chev silverados looks good too, whats your opinions?
