Thanks to all for your input. The rig tows really well currently and I don't think it will be much different adding the scooter and ramp to the back with a couple hundred pounds of tools and fuel in the truck bed.
Don't think I'd like running with the scooter in front of the truck. If it's going to fall off I would rather it be in front of someone besides me, LOL. :D
I know all the stickers run to conservative so there is a little lee way. Never really know how much. Will have to try it on a short trip to find out I guess.
Again,thanks all
