We have had our 2012 rets for almost 2 yrs now and have put just over 6000 miles and 45 nights and have been very happy with it. I have had a couple of issues, Slide needed adjusted, 1 outside speaker went out, and after about 5000 miles I had 1 wheel seal start seeping. Could have been me because the wheel started seeping after I had lubed the axles. We have been very happy with the fit and finish and the bang for the buck.
We are also very blessed to have a factory rep (Sabresam) monitoring this forum and from what I can tell will bend over backwards to assist Sabre owner to resolve any problems. I have had great customer service not only from Sabre/Palomino but also my dealer.
If you have a other questions just ask.
Good luck.
