We are our first trip with new 178. Had a pretty good rainstorm this afternoon. Did not see any problems except that we started having water leaking from the right corner of the slide out panel next. Looking at the picture below, you can see the towel. The actual leak was coming from the right hand corner nearest to the table and front door. The slide out was open during the rain and I assume that somehow water was working from the outside and coming out the lowest point, which would be the right corner.
It continued after the rain ended and the lower right hand corner is still wet. Any suggestions from experienced "podders" would be welcome!
