For your 2008 Jayco Jay Feather Sport 218 Travel Trailer, I recommend going with the:
-Adco Olefin HD All-Climate + Wind RV Cover for Travel Trailer # AD47ZR.
This cover will fit trailers that have an overall length of 20'1" - 22', so this cover will fit perfectly.
Additionally, this cover is also made to accommodate a rooftop air conditioner as well as your awning. Please note that this will not cover the propane in the front of the trailer as it's only designed to cover the trailer... view full answer...
