OK finally ready for a dump truck, been doing dump trailers for years but its time to consolidate no more multiple trips, equipment, materials etc.. Tried a GMC 5500, it was big, good turning radius but its a tank, if I had a little truck to drive around it'd be alright but... Leaning towards a 07, 08, GMC 3500 diesel dump but also looking at Ford 350 and 450, any one have experience with any of these trucks? Reviews? Big difference between 350/450? Haul stone quite a bit, I have a Dodge 3/4 ton and feel like I'm on the edge with the weight all the time, plus just did ball bearings @ 50000 miles and don't trust Dodge anymore! Like cummins but the rest of the truck... F450 little more tow and payload more reassuring, but worse mpg worth a little more heavy duty? Thanks for any reviews or info!
