I am looking at building an off-road (i.e. forests) spray truck for tree spraying. I've seen thread in the past about brush-fire trucks, but can't seem to find what I need. Although a 5 ton would certainly hold more water, I think the added curb weight would just lead to traction problems and sinking in soft ground. The truck would have very little road time when full of water since we use transfer pumps for refilling off road. The question is how much water can I haul safely off-road at low speeds before running into capacity problems? I’ve seen several posts of brush trucks busting front axles off-road and want to avoid that, but when spraying the load gets lightened very quickly so I want to have as much as possible when I pull away for the lakes/rivers. Any wild-firefighters have any idea of when you started having problems?
FYI- Would probably add detroits to both rears to help with traction.
Thanks
