When the temperature drops, an unheated compartment is where the trouble starts: frozen plumbing, dead batteries, cracked fittings. The Xtreme Heaters Large 800W keeps that enclosed space above freezing so your rig comes through winter intact.
-
Bigger space, more heat. The X-Large 1000W is the model Xtreme builds for large skirted RVs and oversized compartments, where an 800W has to work too hard to hold temperature. It protects plumbing through a hard winter and cuts the propane you would otherwise burn keeping the underbelly warm.
-
Winter on, summer off, no tools required. The Quick Release Bracket lets you drop your heater into place when the cold sets in and pull it back out for the season in seconds, leaving only a low-profile bracket behind.
-
A permanent, low-profile home for your heater. The Mounting Bracket bolts your Xtreme Heater into place with four screws and holds it solid through vibration and travel, tucking it neatly into tight compartments.
