I have a 2017 30WRS with 3 cowling pieces - the one in the middle is for the generator, the other two, cover the propane tanks. They are held in with
Southco 19 Series Swell Latch 2.48 Handle Length, Frame Thickness .05 and Up. When I picked up the TH, the final check must have missed that they were not installed correctly. Lost the center one at highway speed, just below Bonners Ferry, Idaho. Luckily, did not hit anyone or break or get run over, and we put it back on and tightened the others. After getting home I called the dealer, they sent me a full package (I also bought a package at Amazon for extras). Then we figured out someone had not stacked the washers correctly in the latches...fixed that and have been traveling since October 8th with no more problems. It's a good system when it's applied correctly. Think I have some of the extras assembled with the washers - could do a picture if you'd like.
