As a few have mentioned..... FlexArmor. It’s not cheap....but pretty darn near “bullet-proof”! If you plan on keeping the RV, it is an option. We had ours done in August down in Mesa,Az. ( ARPRV). Great folks to work with. When the job is complete, there is nothing perforating the roof. All brackets, bases, etc. are put onto roof prior to the spraying of roof material. If you get a leak... it likely “did not” get in through the roof. There are some videos on the net showing the FlexArmor system being applied!
