Your 2018 Jayco Greyhawk Prestige Motorhome is built on a Ford E-450 chassis. The Adco Deluxe RV Windshield Cover for Class C Motorhome, # 290-2507 that you linked to is confirmed to fit your Class C and my preferred available option. I like the privacy screens that let in natural light but make it difficult to see in from the outside. view full answer...
We do not carry the Atlas brand of RV keyless entry doors. I am not sure where would be the place to find the but we do carry other brand keyless latches like the part # 295-000183 for right hand side or part # 295-000185 for the left hand side.
I don't know what RV roof vent you have but we do carry replacements that have remotes like the Fan-Tastic # FV807350. If yours does not have a remote there wouldn't be a way to add a remote to it. view full answer...
The Camco RV Rain Gutter Spouts part # CAM42323 for black or part # CAM42134 for white should be an excellent option for a Jayco Greyhawk whether you are replacing existing or adding new. They simply slide over the existing gutters for an easy install. The 2" extension will do a great job of keeping water away and preventing black streaks. view full answer...
I do see how the Hellwig Helper Springs in the rear could affect the SumoSprings but I don't think there is anything on the J-Ride that would affect fit on the front with the SumoSprings Solo Custom Helper Springs part # SSF-106-47. The J-Ride is already pretty great so you should not really need to add much more to the suspension but the front SumoSprings would still be a nice addition for the 2022 Jayco Greyhawk Prestige. view full answer...
