Tremendous amount of fleet trucks, no way to know which one is best. A lot of them will go to used truck dealers , they get cleaned up , they put some new lipstick on them and double the auction price.
Buyer beware no mater where you buy.
I am not disagreeing with what you stated here. What I questioned was how successful you have been buying a truck at an auction with this logic? My point is if you are being honest, if you take the price of in frame into consideration you just priced your self out of the game.
