Camplux PRO 65,000 BTU RV Tankless Water Heater

A standard 6-gallon tank replacement runs $300 to $500 plus labor — and you still get the same limitations: limited hot water capacity, recovery wait times, and propane waste on reheating. The Camplux PRO eliminates the tank entirely. You get unlimited hot water on demand, anti-freeze protection, and scald prevention in one unit. At $447, you are paying roughly the same as a tank replacement but gaining on-demand performance that actually changes your daily experience.

The Camplux PRO is designed as a direct retrofit for Suburban and Atwood 4-gallon and 6-gallon tank water heaters. It fits into the existing cutout opening, so you do not need to modify your RV wall. That said, every RV has slight variations in plumbing routing and propane connections. We recommend confirming your existing water heater model before ordering. If you need help verifying fitment, contact us — we can walk you through the compatibility check. We are an authorized dealer and we stand behind what we sell.

2.64 GPM is sufficient for a single shower with standard RV fixtures. Most RV showerheads flow between 1.0 and 1.5 GPM, so this unit handles that with capacity to spare. You can run a shower and a sink simultaneously in most setups. If you are running multiple fixtures at once — shower, kitchen sink, and bathroom sink all drawing simultaneously — you may see reduced flow temperature. For typical RV or cabin use with one or two fixtures active, 2.64 GPM works well.

The Camplux PRO carries the manufacturer's standard warranty. Off Grid Vault is an authorized dealer, so warranty claims go through us — not a ticket queue with no response. If the unit arrives and does not perform as specified, our 30-day performance guarantee covers uninstalled returns in original packaging. For field failures after installation, we process the warranty claim directly with the manufacturer on your behalf. You are not left troubleshooting alone with a support line that does not understand RV or mobile applications.

If you are replacing an existing Suburban or Atwood tank water heater, installation is straightforward. The Camplux PRO fits the same cutout, so the physical swap involves disconnecting the old unit, setting the new one in place, and reconnecting propane and water lines. Most mechanically inclined RV owners complete the swap in two to three hours. If you are doing a fresh install in a build rather than a retrofit, plan for additional time to cut the opening and run plumbing. No special tools are required beyond standard RV plumbing and propane wrenches.

The anti-freeze device activates when outdoor temperature drops below freezing and heats the water system to 48 degrees Fahrenheit, then stops. This protects against short-duration freezes and overnight cold snaps — the kind most RV and cabin owners encounter during shoulder seasons. For sustained deep-freeze conditions where temperatures remain well below zero for days, additional insulation on your water lines is still recommended. The anti-freeze function is a safeguard, not a replacement for proper winterization in extreme climates. For typical remote use in the Southwest, Midwest, or Pacific Northwest, it handles the conditions you will actually face.
