What's wrong?
The heat shield on 2018-2022 Thor Motor Coach Vegas and Axis motorhomes is a metal barrier mounted between the chassis muffler and the LP tank. Its job is simple: keep exhaust heat from reaching the propane tank area while the muffler gets hot during normal driving.
On affected motorhomes, Thor Motor Coach says that shield was not installed during production. The company says the shield is required when the space between the LP tank and chassis muffler is less than 18 inches, and the current measurement is 11.8 inches. Without that barrier, the LP tank area is exposed to heat it was supposed to be shielded from.
There is no warning sign before failure. Owners should not expect a dashboard message, sound, smell, or handling change to confirm that the heat shield is missing.
