Do you ship to Sarnia?

Yes. We ship by UPS to Sarnia and every Ontario postal code, with duty, brokerage and the 13% HST covered. The checkout total is the final price.

Will I pay duty, brokerage or HST when my order arrives in Ontario?

No. The RV Fuel Vault is made in the USA, so it qualifies for 0% duty under CUSMA/USMCA, and we cover all customs brokerage and the 13% Ontario HST. Nothing is collected at your door — the checkout total is the final price.

What currency will I pay in?

Checkout is charged in US dollars. Canadian visitors see an approximate Canadian-dollar estimate next to prices, and your card issuer converts the final amount.

Which motorhomes does it fit?

Class A gas coaches on the Ford F53 or Workhorse chassis and Class C coaches on the Ford E-350/E-450 use the Large door. Super C coaches on the Ford F-550/F-600 or Ram 5500 use the Small door (single, or a keyed-alike 2-pack for dual tanks). Mercedes Sprinter van coaches are not compatible. Use Find My Fit to confirm your exact year, make and model.

Should I install it before winter storage?

Yes, ideally. It bolts on in 8–15 minutes with basic hand tools, so a full tank stays full and clean through the storage season — and it stays protected at every overnight stop when you head south for the winter.
