I have 2016 CL21RBS and just returned from 3+ weeks in FL. We had trailered 4-5 hours in heavy rain one day and for the first time got some water in around wheel-well under the slide and some appeared to come from under the fridge (wheel well extends in there as well.)
Believe it or not this is the first real issue that I have had with the camper. We have used it a lot and it has been outstanding quality wise.
I bought it new in April last year (in IN as a leftover) so it is still on warranty. I have the option of having it looked at by a dealer. A tad nervous about having a dealer without any knowledge of LL's make things worse.
Pics show a little water after spraying up into wheel well with hose to test after we got home.
