Our 2015 SLX 264BHW has not had one issue, going into second season I checked under TT for bolt issues etc etc, nothing to report. Also someone earlier noted black and gray water tanks are 32 gallon, but this TT are 39 gallon. Not sure where he got that info.
Prior had 38.5' Keystone Sprinter, wife and I loved extra space and features, but neither of us miss that thing at all due to issues it had, Then had a SLX 154BH, too small and no comfort inside on rainy days. One extreme to the other I guess, but now really happy with the 264BHW, got lots of features and those feature more expensive TTs have we don't even think about...
