What's wrong?
The affected part is the wire harness between the battery and inverter on 2025-2026 Tiffin Open Trail motorhomes with an optional diesel or propane generator. That harness carries battery power to the inverter, which changes battery power into usable AC power for equipment in the coach. The wire has to be large enough to carry the electrical load without building excess heat.
On affected Open Trail motorhomes, the harness was built with 2 gauge wire where the inverter installation guide called for 2/0 wire. The smaller wire is not sized for that load. When current moves between the battery and inverter, the undersized wire can overheat instead of carrying the load as designed. Tiffin's repair replaces that harness with one built with the correct wire gauge.
There is no warning sign before failure. An owner should not expect a warning light, noise, or dashboard message before the harness overheats.
