What's wrong?
The propane lines on affected 2020 Unity motorhomes carry fuel from the propane manifold to the onboard propane appliances. That manifold is the distribution point, and the copper tubing and flexible hoses need to stay open, straight, and properly clamped so propane reaches each appliance at the right flow.
On these motorhomes, the copper tubing at the manifold was installed with twists or kinks. The filing says the flared end of the copper tube was too large, which made it bind inside the flare nut during installation. Some propane hoses were also routed or clamped in a way that put twisting pressure on the hose. Once kinked, the hose can collapse and restrict propane flow.
Owners can notice a propane smell, the sound of propane being released, or weaker propane flow to the appliances. Those are warning signs that the line or hose needs attention before the system is used again.

What's the safety risk?
A twist or kink in the propane line can let propane leak and raise the risk of fire. If you smell propane, hear gas escaping, or notice reduced propane flow to LP appliances, stop using propane appliances, shut off the supply if safe, ventilate, and contact the dealer. Repair is free at any franchised Unity dealer.
What should I do?
- Check your VIN to confirm your 2020 Unity U24FX, U24CB, W24RTB, W24MB, W24FTB, U24MB, U24TB, S24CB, U24IB, or U24RL motorhome is included in this recall.
- Contact a franchised Unity dealer to schedule the free propane-line inspection and repair.
- Ask the dealer to inspect and correct the kinked or twisted copper propane tubing and rubber hoses, which addresses the propane-leak fire risk.
- Bring the recall notice if Unity has mailed one. If not, reference recall number 20V054 when you call.
- Avoid using LP appliances until the propane tubing and hose installation has been inspected and corrected.
What happens at the repair
At the dealer or RV service center, a Unity technician inspects the copper propane tubing and rubber hose installation for twisted or kinked routing, then corrects the installation as needed. The recall repair is free, including parts and labor. Unity's reimbursement plan says retail owners can work through their selling dealer or an RV service center. If you've already paid for this repair, Unity reimburses the retail owner or pays the servicing center directly.
