Real photos from Dynamax owners who installed The RV Fuel Vault on their own rig.
Found Scott and his company and immediately got on the list for the first batch of the RV Fuel Vault. Scott has been great and is passionate about solving problems like this one. Great people, company, and product. Jeff
Looks really good - installation was a little challenging on the front tank because the fuel fill is mounted on a metal plate not like the rear tank. Had to predrill the holes to accept the #12 screws. I ended up snapping 2 screws before the predrill. I really like the look and feel comfortable that the tanks won’t be messed with. Also like that they are keyed the same. Awesome - Thanks
