We have a 2011 NT30RLSS TT. Noticed on a trip to the coast that the skirting/fenders were really flapping in a strong cross wind. Upon arrival at the camp ground, 3 screws had pulled through above the wheels. This skirting is very flimmsey and not secured to the trailer very well. I got some L Brackets and bolted them to the flange of the skirting and screwed to the bottom of the floor. Sealed up everything. Now it won't move at all. It took a couple of hours and under $20. The screws that pulled through, I just got some fender washers, painted them white and re-screwed them. Everything seems much more secure now. Heartland QC really dropped the ball on this. This was a no-brainer......
