If the gap is primarily on one side you can adjust it per the below thread. If it’s on both sides I wouldn’t worry about it too much if you haven’t had any issues thus far. Would just be nice to address when you are at the shop already. I had emailed them about solutions for those of us with holes on both sides but they never got back to me. To be fair, I have only had a wet mattress one time and I was parked nose down (camper closed, no issues with the tent up) in a crazy WA rainstorm. Since then I’ve been parking level I haven’t had any issues.
