Hitch mounted motorcycle carrier on class c

That rack does not look all that heavy duty to me. The problem may be that the 400lb bike and the hitch at 80 lbs mounted 10 feet behind the rear axle will be like a lever and may remove more weight from the front axle than would be considered safe. Plus the 480lbs bounching 10 feet behind the rear axle will multiply the weight and could fail the rack your using causing the bike to end up on the road. Without having the motorhome run over scales to get the before bike and after bike weights your not going to know for sure what the weights hanging out back will do to the front steering. I would think a trailer like Desert Captin is describing would be a lot safer for your transporting. Just my opinion as an Ex-Weigh-It-Guy.
