RV AC Heat Strips

A heat strip is a resistance heater that mounts in a heat-ready ceiling assembly and runs off shore power. About 5,600 BTU, enough to take the chill off a spring morning, not enough to replace the furnace. The 38203-4551 fits medium and low profile units (Mach 3, 15, 10); the 37203-4551 fits the ultra-low Mach 8 line. It will not fit a cool-only ceiling assembly. See Heat Strip vs Heat Pump.
