I probably am over thinking it. Yeah the front wheels are definitely on the bed of the truck so thats not an issue, I just wanted to give a little more room for comfort is all.
I have zero concern with the weight of the quad in the back of the truck.
I don't want to use the tailgate soley because it will be in the down position while driving, and I don't want any rock chips.
There is a point in time while loading that the entire quad's weight is on the tri-fold ramp. However I am guess half the weight is still support by the ground and half by the truck correct? Because its distributed over the entirety of the ramp?
