New BD Owner
We picked up our 20BD in September after owning a 21RWS (hated the slide, but that's a longer story). So far we have spent probably 20 nights in it, but no dry camping or boondocking. We have had no warranty issues and only one minor cosmetic issue. The one knock we would have is that it certainly has less storage than the 21RWS which is challenging for dishes and pans as well as clothes for winter camping. There is one mod in the Mods thread regarding putting a door into the area under the back bench that I am going to do to better access that space. Generally we are very happy with it for two people and a Pomeranian. I have camped with 120V 15A power down into the 20's with no problems.
I have made a few mods like a better kitchen faucet, electronic door lock, battery monitor, 12v LED lights with switches (you generally don't need so much light), and TPMS. Will likely go to lithium batteries next year under the bed storage area and an additional solar panel. We have the on-board generator but have not had to use it much.
As other reviewers noted it is a little tongue heavy. My F150 with the heavy tow package definitely knows it is there, but we went with the Hensley Arrow which is the best thing on the market for anti-sway. It is very easy to maneuver.
