Topper and Vent Options Offered By Dealer for New Purchase

I went with the Maxx Air for the fan cover, their 6 year Warranty and the LESS than 5% airflow restriction. All their covers are constructed of high density polyethylene with maximum UV inhibitors,they cost less and last longer than the Fantastic Vent Cover

Unlike the Fantastic Vent covers that only have a 3 year Warranty they seem to not Last that long.

I have 4 other Maxx Air Covers on my RV that are 7 years old and show no sign of chalking or brittleness,it sits outside here in sunny So Cal.
