On my previous coach and on the Challenger I had the dealer install vent covers, on their dime, as a condition of sale. I also had them install tire valve extensions as a condition of sale as well. The items were on the coach when I arrived for the PDI.

I ordered our Vegas without the power vents, then ordered a power vent online and installed it myself. It has a rain sensor and remote, for about the same cost as the upgrade fan vent. Both front and back vents are prewired in the Vegas for power vents. I installed covers over the bedroom and bathroom vents.
Bad decisions make great stories!
