I have a 2012 32QBTS travel trailer. Warranty issues. I upgraded to dual pane windows and a few of them did not open and close correctly - one would not latch shut and had to be replaced. Water pump would cycle on and off because of a bad check valve in the pump and needed to be replaced.
I bought it in the winter and was pulling it home across the country and camping in it on the way home and the furnance would run almost continually with not much heat. I pulled the return cover and noticed that one of the output duct block off plates (used when duct work is not attached) was missing so the hot air output at the furnance was just blowing out at the furnance and right back into the intake. I bought a piece of sheet metal and cut it to match and block off the opening which solved the issue. Six months later and the furnance would just quit working. Brought it in for warranty and the found a loose wire up in the A/C unit.
Now it is in for a rear bunk slide-out that is catching and not going out.
These issues could happen to any model. All but the water pump could have been avoided by better quality control and slowing down on construction. Seems to be pretty typical in the RV industry.
Overall I feel Sabre is high quality. I seem to be having worse luck than most.
