What Customers Say
Real reviews from real installations.
Easy install and looks great
— Steve Jensen
Great product and easy installation. The door looks stock on my rig and helps me know when I fill up in the only one using my gas.
— Kenneth Schoenhofen
The fuel vault shipped fast and were easy to install. Just remove the old screws, place the Fuel Vault over the existing surround and use the security screws to fasten the vault in place. Use a star pattern when putting in the screws. The side benefit is that they look great!
— Dave Simonson
Was looking for an option for a way to lock my fuel caps on my new rig. Came across The RV Fuel Vault, decided to place an order for two covers, within 2 hours of placing my order I received a phone call from them thanking me for my purchase and they will have them shipped out asap. Great customer service! The covers arrived to me within 10 days, I was concerned about duty or tariffs but that was not an issue. Just finished the install, straight forward and simple. The rig looks so much cleaner without the green caps sticking out like a sore thumb. I would recommend this product to everyone.

What an excellent product!!! Took me less than 10 minutes to install. HIGHLY recommend this locking cover. This is on my 2021 Jayco Redhawk 24B Class C. It’s just BADASS looking.
— Jeff Rettig
This is a must have for RV’s that don’t have a locking fuel door. The quality is amazing. Fitment was spot on. No additional drilling, just remove the existing screws and use the existing holes. Made in the USA. I highly recommend this product.

Frequently Asked Questions
What is a locking hatch door?
+
A locking hatch is a small keyed access door you mount into a wall, panel, or skirting. It gives you a lockable pass-through for cords, hoses, and air lines, or quick outside access to something stored inside — without opening the main door.
What size hole do I cut for a LockingHatch?
+
Small door: 4-7/8" wide × 5-1/8" tall opening (bezel 7-1/4" × 6-7/8"). Large door: 4-7/8" wide × 6" tall opening (bezel 7-1/8" × 8-1/8"). Use the free printable, true-scale template on the Find My Cutout page.
Can I install it myself?
+
Yes. It is a basic DIY job with a drill, a jigsaw or oscillating tool, sealant, and the right screws for the surface. Wood, metal, vinyl-sided, and fiberglass walls are all covered in our fastener guide.
What can I mount a locking hatch on?
+
Enclosed and V-nose cargo trailers, landscape and lawn-care trailers, job-site work trailers, truck caps and service bodies, sheds, workshops, garages, carports and pole barns, and mobile-home skirting.
What is it made of?
+
3/16" fiber-filled polymer that is UV-stabilized and corrosion-proof, with a tamper-resistant keyed lock and 2 keys. Multi-packs are keyed alike. Made in Sarasota, Florida with a limited lifetime warranty.
Are multi-pack doors keyed alike?
+
Yes. The 2-pack and 3-pack doors are keyed alike, so one key opens every door in the pack.
How much is shipping?
+
Shipping is charged at the live UPS rate for your address, with no markup, calculated at checkout.
