Someone was using a Tilt-a-Rack to carry a Yamaha (from the Roadtrek Group - I think it was a Chevy).
I don't know much about this. My guess is that you have to add the weight of your motorcycle, the rack & spare tire and mount & make sure the hitch is rated for the load. Roadtrek's (previous year) SS-Agile hitch had a Towing - tongue weight of 500lbs with a note that "A weight distribulting hitch is required for tongue weights over 200 Kg/400 lbs."
It might be similar with your Pleasure-Way.
a Pleasure Way Ascent Very nice!
