Thank you all for the input. Vier is thinking about a selling hitch mount, like a bike carrier but sized for the 4 wheels (think 2 inch tube steel from receiver and two aluminum channels bolted to the 2 inch tube for the wheels, running parallel to back bumper). My biggest issues with that is having to have a receiver added to the trailer and how far out it will stick behind the trailer. So, 2d idea. Same orientation, same pulley set up to raise the quad, but then make two wheel scoops that mount on the back bumper to set back wheels into and to take the weight, secured to the ladder to hold in vertical position. PS -the 2 seater, no motor, around 125 lbs
