Equipment:recreational vehicle/trailer:lpg systems:lines and fittings
Problem: Thor Motor Coach (TMC) is recalling certain 2018 Thor Ace 27.2 recreational vehicles. The rubber liquid propane (LP) hose may sag and contact the tire in the wheel well.
Risk: Contact with the tire may cause the LP hose to leak, increasing the risk of a fire.
Fix: TMC will notify owners, and dealers will inspect the rubber LP hose and replace it as necessary. Dealers will install additional p-clamps or relocate the existing p-clamps to properly secure the hose, free of charge. The recall began on August 22, 2018.

Equipment
Problem: Thor Motor Coach (Thor) is recalling various 2003-2018 recreational vehicles, equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. See a list of the affected trailer models at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V758-5764.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.
