Thanks "Emptyoilcan" and "Grigg" for such quick responses. All info is helpful. We are looking only for minimal highway speed and not sure if the original would get us there. Some of the wineries are a couple of hours by car.
The truck already has the dump hoist so it is what it is and that is part of what attracted us to it. Unloading a pick up truck full of mulch or gravel is exhausting with a shovel. Very interesting comment reqarding the insurance on the dumps. We will definately look into that.
