What's wrong?
The cargo carrying capacity label on a 2017-2018 Thor Motor Coach motorhome tells an owner how much weight the coach is built to carry. That label includes water capacity information for the water heater and fresh water tank, because water adds weight and affects how the motorhome should be loaded.
On affected Axis, Windsport, Venetian, Miramar, Hurricane, Challenger, Chateau, Four Winds, Tuscany, Vegas, and Palazzo motorhomes, that label lists the wrong water capacity. The coach itself is not described as having a defective tank or heater. The defect is the printed loading information: if the water amount is wrong, the owner is working from the wrong carrying-capacity label.
There is no warning sign before failure. This is a label accuracy issue, so an owner will not feel a change in steering, braking, or engine operation that points to the incorrect cargo carrying capacity label.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorhome is included.
What's the safety risk?
The incorrect water capacity label can lead an owner to overload the motorhome, increasing the risk of a crash. Until the corrected label is installed, use conservative water loading and confirm capacity before travel. Repair is free at any franchised Thor Motor Coach dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Thor Motor Coach Axis, Windsport, Venetian, Miramar, Hurricane, Challenger, Chateau, Four Winds, Tuscany, Vegas, or Palazzo motorhome is included in this recall.
- Contact Thor Motor Coach customer service or a franchised Thor Motor Coach dealer to get the corrected cargo-carrying-capacity label that fixes the incorrect water-capacity information.
- Reference recall number 17V634 and Thor Motor Coach recall RC000147 when you call.
- Bring the recall notice if Thor Motor Coach mailed one, or keep the corrected label with the motorhome after it arrives.
- Avoid overloading the motorhome until the corrected label is installed and the water-capacity information is verified.
What happens at the repair
Thor Motor Coach sends corrected cargo carrying capacity labels to owners at no charge. The corrected labels replace the incorrect water capacity information for the water heater or fresh water tank, so the motorhome's capacity label matches the required information. Parts and labor are covered under the recall. If you already paid to correct this label issue, reimbursement is handled through Thor Motor Coach's normal warranty claim process rather than a separate recall reimbursement program. Ask Thor Motor Coach customer service or the service desk how that warranty claim applies to your prior paperwork.
