Water Leaks
I have a 2016 Four Winds 33SW and I had the entire RV resealed last year. Dicor and Eternabond tape on the roof and commercial automotive sealant on all of the seams. I believe everyone with a new RV should use the Eternabond Tape on all of the roof seams and joints. And Dicor the edges of the tape after installation. No leaks at all and quieter going down the road.
I also discovered two of the long screws securing the air conditioners loose and before securing them back down I resealed the AC units.
Water is the silent destroyer of an RV. It's rotting the structure silently and you will have no idea.
