Anyone tow a Can-Am Spyder behind their motorhome?

As others have said an enclosed trailer is the way to go. A 6x12 (marginal) or 7x12 (better) with tandem axles and electric brakes with a rear ramp and side door. Keep in mind that the spyder is 62in wide so the width of the rear door is important and it is 5 ft high. An enclosed trailer gives you protection from the elements and security while towing and at your campsite. These bikes are expensive so take care of it. They weigh more than 1000 lbs so keep that in mind also. Lots of spyder info in these forums:
