travel in freezing weather

I have stayed in those same parks in May and the temps were high 20s and low 30s for a few hours at night. Never did anything and never had a problem. I have chipped a little ice in Minnesota to disconnect a water hose in September and never had a problem with the lines freezing. A fresh water tank is a lot of water as are the black and gray tanks. It would take a long time for that much liquid to freeze at temps only slightly below 32F. Pipes are mostly inside in most units and are going to retain the ambient temperatures for quite a while. You probably will be wearing short sleeves in the daytime.

High twenties for a few hours overnight won't freeze you up. Your heat will take care of things.

Hi

Spent several nights in Arkansas last December before wanting to move when it was freezing and now thinking about what we intend to do next winter. We were on a site which is unusual for us with full hook up.
1.At night we left on a fan heater on a low setting to keep inside above freezing. We do not like it hot at night!
2. Dumped the grey water in the evening so tank and lines empty. kept a few 5 litre bottles of fresh water to use.
3.Dumped the black tank in the evening and then left on line to flow. Urine should not freeze and flush down with a good lot of bottle water for fast flow out. In the morning check the dump valve is free and give the system a good flush. (you have a risk of small amount of ice on the valve sides stopping it moving/closing.
4.Disconnect the shore water and ensure the line is empty so it does not freeze!
5. We also fitted pipe wrap around the dump lines from the tanks and put insulation between the RV side and the grey tank - pushed up polystyrene packaging we had from a parcel which stayed there even driving.
6. Try and park your RV so the sun shines on it during the day and not under trees as you may in the summer for shade. This makes big difference during he day.

We had one morning problem - the day we were leaving! The black dump valve was stuck from ice on the insides and would not move. Used some cardboard to make a surround outside and put the fan heater there for an hour whilst we had breakfast.
This winter intend fitting trace heating to the lines after the tanks and putting a heater pad on the bottom, or trying to wrap around the tanks bottom the trace heating. Want to boon dock a lot so power will be a problem.
Oh one other thought is that some sites charge extra for a second electric plug in, so you want to be able to do it on you main supply and run your cable inside to your main panel. We were lucky in December we had an all in price for a month with electric at a great rate - 275 dollars! North of Mountain View at Sylamore Creek.

"overnight temps are in the high 20's-low 30's."

We've done this many times; your holding tanks will be okay; We've never had anything freeze in those temps; We do run an electric space heater to take the
chill out of the air.

Even tho I run a Class A gas motorhome, low temps are low temps...and plastic pipes are plastic pipes.

I (we) have traveled or overnighted in temps as low as 14 degrees. Knowing our RV is really not made for these kind of temps, what we did was:

(Overnight):Turn on the propane heater.(Presuming you have a full or almost full propane tank(s).

Using a space heater, put it on the floor, open the kitchen cabinets and let that run all nite....to keep the piping under there from icing up.

Run a trickle of water in the kitchen sink and bathroom sink. Mix the hot and cold as well as you can.

Now that is for overnight. When on the road, no problems that I encountered, the dash heater kept us comfortable....at least for the 4 hours we were on the road until we hit the Phoenix AZ area...where temps were around 70.

Arrived at our destination intact...or so we thought. Set up...all was well. First day...all was well. Next morning, the toilet supply hose blew out.Like it was cut with a knife...about 2 inches long. Niagara Falls outside the trailer, bathroom carpet soaked. I guess ice formed in there....and that was a good 2 feet from the outer wall. Cannot explain it. Anyway...Home Depot in Mesa was open at 7AM...got a garden hose cut it to size and made the replacement. Took 3 days for the carpet to dry out. So....y'never know.
