Temp. go before freezing pipes on class a

-5 c (23 f) if the RV is occupied and the furnace is being used.

If using the RV, down to the mid 20's isn't a big deal as the heat will bleed out and keep the underbelly from freezing. (if there are exposed pipes, such as for the black/gray tanks, you will want those fully drained and if on a full hookup site, leave the valves open on cold nights)

If the RV is in storage (ie: furnace isn't heating the rig), even upper 20's gets questionable.

“Seriously?“ Yes, seriously. Tooooo expensive to repair. Ruins a trip.

Most any RV is fine down to 25 overnight while in use. Your Class A I would hope could go a bit lower. Unless the manufacturer gives a specific rating you will need to just go and find out. If you do have a minor freeze up you will need to add heat where needed, head for warmer climate, or find a heated service bay to winterize or add freeze protection.

I'm sure I've read on this forum where people have camped in single digit temps successfully.

Not all RVs put water pipes or tanks inside the heated space. Where they're located does make a BIG difference.

If camped in freezing cold weather, it's a good idea to fill the fresh water tank as it acts as a 'heat sink' for the basement.

I've camped when the lows were in the teens in New Mexico. Of course I have basement heat so all was toasty.

Before I was able to secure indoor storage in TN, I had to put the coach in a RV park in February of 2015. It was a cold one too! I used the diesel-fired Espar furnace for 30 days and it used 100 gallons of fuel. I'm glad that I have a 230 gallon fuel tank!

Safe travels,

Any weather prediction of a low of 30F causes me to take safeguards. I don’t want the hassle or expense of repairs.

There is a lot of latent heat in the water in the tank and lines. As a general rule you don't need to worry about lines freezing up unless you're facing a "hard freeze" which is defined by the temps dropping into the upper 20's (or below) for more than 2 to 3 hours. I've camped in the winter in my RVs and never had a problem following this rule.

32 degrees F. It all depends on how long the RV will remain at the temperature. 28 degrees overnight should be OK. 26 degrees overnight I'd start to worry. That my $.03.
