>>>My scooter weighs about 280 lbs <<<
My goodness man, what are you riding??? My 1975 batavus is only 107lbs and other than the lights, there's not a piece of plastic on it. It's all steel. I'm 250lbs. I doubt that your 'ped could even go with me on it. As for the trailer idea. I did the same thing myself once. ONCE!!! Everything I had in the back stunk of gas and had a slight oily residue on it. It may not seem like it, but there is quite a bit of unburned oil coming out of the pipe, and after 15-20 miles it'll be all over whatever is behind you.
