Keep the space under your RV above freezing. Xtreme Heaters are compact, thermostat-controlled heaters (on at 40°F, off at 55°F) built for enclosed spaces, like the area under your rig once your AirSkirts are up. Choose the 800W for most RVs or the 1000W for larger rigs and oversized compartments, and add a bracket to mount it.
