Fi, I'll try to get some "Chip-Tarp Lasagna" today. It takes a minute to set up per layer, but saves a lot of off-loading, using gravity, and cutting friction.
My chip truck is mostly for logs these days, and I often drive my service body with box to haul the mini-loader around, sometimes chipping on-site, or into the box and unloading onsite, otherwise at home or a friends. Its the wet season, and I can manage my service body into much tighter places than my chip truck, its easier to drive, and is kid-compatible (the chip truck is to loud/ bumpy/ stinky for a 6 Y.O.---I have an exhaust leak at the maniifold, so Its a bit stinking waiting at a light, in the mind of a 6 y.o)
Hydraulic would be great, but I would probably lose 500-1000 pounds truck capacity to the dump bed and hoist, plus I simply don't have a dump in that F450.
Chip-Tarp Lasagna makes unloading as fast as you decide by how many layers you build.
If I'm going to be doing a big removal, or have a place to get the chip truck in and out, I'll definitely go for hydraulic dumping, but the size is a hassle in my market, at times.
Like the "Magic Cut", great for some situations, and the traditional approach is always available.
When you are unloading chips by hand, you have time to think of ways to make it faster and easier. When its faster and easier, you have less time to think, you just get it done.
Fi, what is your weight capacity for chips in that truck?
