Looking at this for a while now. These trucks hold there value! I am almost leaning towards new. Dealers have located alot of 450 truck, mostly ford, all but one has a v10 i think, everything else is diesel. Also the ford seems to beat the dodge in price right now with sale, incentives, ect but I understand they want the 13's off the lot. Only thing I dont like is everything is white. I am tired of everything else out there being white. So what is the main difference of a 450 vs 550 truck? Is it worth the extra money? Truck used for mainly landscape. Haul the few ton of rock to small jobs, mulch, dirt, maybe make a leaf box in the fall. Possible to put on a sander in the winter..not sure but then winter time truck will sit unless it snows - probably use it for the side walk cres, little blowers, spreader, a few bags of ice melt.
