Hitch mounted motorcycle carrier on class c

I have a 24' Class C and carry a KLR250 on an 80 lb rack. Total weight is 380 lbs and I went to a frame shop and had them weld braces on the extensions and put air bags on. The static weight is no problem but the constant pounding over bumpy roads or the speed bump you dont see will be. According to the Flying J scales the 380 lbs subtracted 200 lbs from the front and added 580 lbs to the rear. Your overhang is longer so it will be even more dramatic. I dont carry full water and pack light in the storage compartment and leave the spare at home. The other down side is loading the bike if the campsite is not level. All that said I have hauled it around the country for the last 15000 miles without a problem and have gotten allot of use from it but still feel a trailer would be easier on the rig and my nerves and if I had a travel companion to help backup in tight situations I would go that way.
