We have a 2013 Northwood MFG Fox Mountain 5th wheel. We've had very few issues in the 5 seasons of camping. We would like to get another trailer, 5th wheel or TT, but we're not sure if we want to risk getting a POS. At this point in time it looks like it would be another NW or maybe Outdoor RV unit. They just seem to have way fewer big issues. They still have the small issue stuff like the rest.
Problem is they don't have a floor plan we want. We would prefer something along the lines of a Grand Design 303RLS. After looking at Grand Design and spending the better part of 3 years reading their owners forum, I've come to the conclusion that they are really just another Elkhart ID RV. Great customer service, but I got that at NW. What I want is an RV that I don't need great customer service. Right now we're just staying put as we've had no issues other than routine maintenance in the last 4.5 years of use.
Many other owners have had the same good fortune as we've had with other brands. But many have had worse problems. It's really a **** shoot in the end.
