Real photos from Grand Design owners who installed The RV Fuel Vault on their own rig.
Although I was admittedly a bit nervous screwing anything into my just purchased “43,” the designer/owner graciously provided me some guidance by email and phone and pointed me to a fellow Lineage owner’s/installer’s installation feedback on the rig’s owners’ forum. It was ultimately a super easy install, taking me maybe 20 minutes for 3 “Vaults.” I even created an installation feedback document for our forum. Buy these and sleep easier at night with reduced risk of vandalism and other criminal activities.
This product is perfect for my RV. It fits like it came from the factory this way. My experience with RV fuel vault team has been a very good experience. Good communication great follow up. I’m very satisfied with this upgrade and it looks amazing!
