- Kubota M59, Kubota L3800, Grasshopper 428D, Topkick dump truck, 3500 dump truck, 10 ton trailer, more lighter trailers.
I had a 95 k3500 mason dump with 350 and 4l80e trans. I got more like 7-8mpg. Idk how your getting 12 with a bed the shape of a box. My 2012 suburban hardly even gets 12mpg.
On a side note my state requires commercial car insurance on any dump truck and that first year it cost me $1400..for a truck I paid $800 for. I almost sold it after that. After about 5yrs it was down to about $600 a year. I have no accident or tickets on my record for the previous 10yrs. I also dont live in a city. I'm glad the truck is gone now as a trailer does nearly the same as a mason dump with less expenses.
My ton with a 6.5 turbo diesel averaged 11 mpg loaded or empty.
