10 feet is ok you will always have your feet touching the ramp except when the engine passes the edge of the ramp that is only seconds so should not be dangerous I have a split 10 footer STEEL ramp ( two lengths) I also suggest put some feet under the middle where you connect both ramp to stop the wow in the ramp and the truck suspension from going down too much and finally and I speak from experience buy a cheap 2000 lbs winch mount it on a 2x4 across the front of the truck box secure it somehow and winch the bike up. till you do it you do not realize how safer it is versus bike power you can pull back from the box using the bike weight and use the front brake to control the descent let me know if I can help you with that project. hell I might even sell you my system if you want as I have sold the truck
I also suggest the lockdown system to hold the bike in the truck box it require NO STRAPS because the frame is held from the bottom to the platform and the bike does not pogo at all
I am interested. Safety is no accident. Pictures of the whole set up please.
