If a concern is cost. Remember a motor coach will cost more to maintain and insurance and you still need to hook up a tow vehicle.
A 5th wheel tends to cost more than a travel trailer apples to apples.
IMHO. choosing a travel trailer length & weight come first. Floor plan comes second.Hitching up should not be such a big deal. Like a previous person said once you have set it up the settings and routine to hitch and unhitch will be the same for the duration. Spend time finding the floor plan you like.
As for hauling the bike. I would rather go with hauling it in the back bed of the truck rather than going with a toy hauler. Provided the bike fits into the bed of the truck. ramps can be purchased cheap.
How to on loading bit into the bed of a truck securely.
Good luck.
