This trailer had toppers for the slides. I've never had noise problems in almost 5 years and 46 different states.
The vents for my first TT did not have vent covers. In a modest rain, water would leak in through the vents. We had to make sure we covered the vents whenever we were away from the TT for a day trip. More than once we left on a hot no cloud in the sky no prediction of rain day, leaving the vents open and returned to a wet bed and wet floor in the TT.
I purchased MaxxAir II Vent covers for the three vents in this TT for about $40 each. They were the easiest thing I've ever installed on my RV.
