New Moto Guzzi Door Mats Available Now
Though this "trailer" doesn't add any weight to the "towing" vehicle, it still adds overhang and increases tail swing, which most RVs all ready have too much of.
My concern is the blasting things take when trailered for long distances. My friends MG is very mint and beautiful but it was behind an RV for a few summers before he got it and it really shows. I think a bike would take a beating as well. A covered trailer would be so much better and more space for "stuff".
