I have a 2010 Wildcat 25RL and other than the typical issues that RV's experience it has been ok. We also bought it because of the opposing slides which take the 25RL's convenient length and makes it much more spacious. We do not regret this choice.
For your second question regarding a motorcycle rack, it can be done. I have a motorcycle rack installed on a 2" receiver. This receiver was a factory option but not meant to handle a motorcycle's weight...probably just a bike rack etc. But I took the 5W to a well established local hitch shop and they modified and reinforced it to be able to handle up to 500#. My Honda scooter weighs 309# and the motorcycle rack I chose weighs about 100# for a combined 409# and works well. Nothing that $$ and the will can't make happen.
