I have a '91 F450 Dumptruck w/ a 12' bed that I am considering using as a daily work truck for my lawn route. My F150 does fine pulling the 16' V-Nose but it seems I am always dueing sometype of extra work where I have to put shrub clippings, tree limbs, old plants, dead flowers and stuff in the back of my truck. My current truck (V6 5spd) is only getting 11 MPG. The F450 has a big 460 that pulls great, and has decent power for a big truck but when we haul dirt or the big tractor we are always having to fill up. Do any of you guys run a truck like this daily? Eventually I'd like to get a 20 or 24' enclosed to keep all the mowers in so this size truck would come in handy.
