One thing to bear in mind is the line that feeds water from from the freshwater tank to the pump. Ours is above all the tanks, and no way to reach it. We have tank heaters and a heat tape wrapped around the (long) drain tube from the freshwater tank, and our pump & accumulator are in the same compartment with the water heater (something I wish was true of all RVs!), so even with exposed tanks we have been able to camp down to & just below freezing (overnight) temperatures - of course, temperatures rose at least to the upper 40s in the daytime. However, one night in mid-October in West Yellowstone, our water line to the pump froze up - turned out the overnight low was 16! So we now know our water system's tolerance. (Fortunately nothing broke, and the line thawed out over the next day.)

I wonder how hard it would be to locate and install waste tank bottom-mount heating pads and made-to-fit insulation blankets. I think many class C's use the same size waste tanks given how well they fit and attach to the frame of an E350 & E450. If the tanks are a standard item, then the bottom-mount heating pads and insulation blanks on our rig may also be standard off-the-shelf items. Just buy and install, add a 12V supply with an on/off switch and you will be well prepared for much colder temps.

Our Phoenix Cruiser 2350 two waste tanks are 35 gallons and 23 gallons. Phoenix USA uses the same exact tanks on all 9 of their models going back at least 11 years now. The floor plan dictates which tank is gray and which tank is black. Phoenix heats and insulates all tanks identically, I assume with purchased kits. CLICK HERE to see a few pictures of our insulated waste tanks. The insulation blankets appear to be custom-fit.

What is the tank capacities the rest of you all have on your brand rigs?

Consider a radiant heater pointing it at the valves.

You should be ok to 27 f. Local temperatures can vary a lot from the forecast.

Ron,

Yes. I am going to install heat pads on the waste tanks and valve pipes. Its not especially difficult. It just takes time.

I debated installing insulation around the tanks. I never imagined there might be off the shelf parts. I will dfinately check it out.

Kknowlton,

Our fresh water tank and pump are inside the RV under the rear bed. Two heat ducts pass thru the compartment. I suspect the fresh water would be okay down to 20 degrees for sure, perhaps much less, depending on how much we ran the furnace rather than an electric space heater.
