What's wrong?
The fuel tank on 2025-2026 Tiffin GT1, GH2, and GH1 motorhomes stores diesel fuel and feeds it to the engine. It sits below the floor, so parts fastened through that floor need enough clearance to stay clear of the tank.
On affected motorhomes, components were attached to the sheet metal floor above the fuel tank with screws of the wrong length. In floorplans with tight clearance above the tank, a screw can reach the top of the tank and puncture it during manufacturing. That puncture leaves an opening where diesel fuel can leak.
Owners can notice fuel under the motorhome after filling the tank to full. A fuel odor when the tank is not being filled is another warning sign that fuel is escaping from the tank area.

What should I do?
- Check your VIN to confirm your 2025-2026 Tiffin GT1, GH2, or GH1 motorhome is included in this recall.
- Park the motorhome outside and away from structures until the fuel-tank repair is complete.
- Contact a franchised Tiffin dealer to schedule the free fuel-tank inspection and any needed replacement for the fuel leak risk.
- Bring the recall notice if Tiffin has mailed one. If not, reference recall number 26V338 when you call.
- Avoid ignition sources near the motorhome and do not use it if you smell fuel before the repair.
What happens at the repair
Until the recall repair is complete, keep the motorhome parked outside and away from structures. At the dealer, a Tiffin technician inspects the fuel tank for damage from the manufacturing screw issue and replaces the tank if damage is found. Parts and labor are covered under the recall. Tiffin's standard reimbursement plan applies to documented fuel tank repairs paid before the recall notice. Bring prior repair paperwork to the service desk so Tiffin can review the claim.
