I have a chevy 3500 dump truck that I am looking for a set of ramps. My goal is to be able to load two walk behind Torro's on the back without a trailer. I live in a summer resort area- it is a pain pulling a 16' trailer around (and I worry about my help when there out) The bed is a good 4ft. high, so I need long ramps for small incline. I'm thinking of trying to buy those ramps off of u-haul trucks there heavy duty. Does any one know where to order some ramps- catalogs? I've tried 2x16 with a ramp kit. I can get the mower up but its a pain to get down.
