Thank you, Ken. This is really what I believed. I was just trying to think of something easier than unhitching the truck and using ramps to get the scooter out of the back of the truck. I appreciate your information.

First is the issue of it will lihtenyour hitch weight, which you do not normally want. Next are the stress issues. Hanging a static weight out at the end of a lever arm is one thing, but as soon as you start to move down the road,you have dynamic forces involved now. The distance from the scooter back to the support pont on the trailer frame will be something close to 2 feet. The scoter support or bracket will probably weight a good 100# plus the scooter, say 200# for a total weight of 300# hanging 2 feet back from the frame. The moment arm will equate to about 600 #/ft for a static load. When moving down the road, the rar of the trailer will be moving up and down. When it moves, the weight will be seeing an acceleration and a deceleration which will result is an intermediate force that is several times the static forces. I know you will see people with scooters and such on the back of a rear monted hitch, but I have also seen carriers destroyed with only a couple of bicycles on them. Short story is to not add the hitch or carrier to the trailer if you care about the trailer or scooter. Asa note, I am a mechanical engineer by profession. while I have spent my career in heat transferand thermodynamics, I still understand stress es, statics and dynamics.

Along with it came a hitch mount mechanism which you can put into the hitch receiver of your pickup to haul the scooter on the back of the truck. The metal scooter and hauling mechanism are not light. I'd like to be able to take the scooter on trips with me. I'm wondering if it would be folly to have a receiver put on the rear end of my 28' foot 72 continental rocket so I could haul the scooter on the back of the trailer. I've learned the importance of tongue weight and not hauling full water tanks, etc. so I'm wondering if this would put too much weight on the back of the trailer causing trouble for towing, etc. I can get ramps and put the scooter in the back of the pick up but it would be far more convenient to just put the already purchased devise on the back of the trailer. I have an equalizer hitch set up to hitch the trailer to the 3/4 ton Ford truck but even with it I still have some trouble with passing semi-trucks causing drag on me so I'm cautious about mounting too much weight at the back of the trailer. What are your thoughts? Thanks. Chris
