I have a 2017 22rr and I really like it. When I picked it up (winter of 2016) I took extra time inspecting the unit. I used a check list. The tech was a little annoyed but I'm glad I did it. There were a few spots on the exterior that needed more silicone, a few of the cabinet door hinges were loose and there was a small leak under the kitchen sink. They fixed everything and I was on my way. I have not had any problems after that ( Later on I did reinforce the shower floor ).
The unit I got does not have exterior gas line, exterior shower, power stabilizing jacks and the patio deck. I got a great deal on this unit which is why I bought it instead of ordering one with all the options. I purchased mine from Iowa (one-thousand miles away from me).
I would like to upgrade to a larger unit but that would also require upgrading my truck. I chose the 22rr because of the front bedroom and the ability to use the kitchen, bathroom and bedroom when traveling while the harley is inside.
My bike is lowered (I'm 5'7") and it was too steep. I attached three swing down leveling legs on the ramp door and use a 4" aluminum ramp. I got the idea from here
