With a water tank above the floor/under the bed, and adjacent water pump, what is the most vulnerable freeze point? (Assuming waste tanks are empty or nearly so.)

Our forecast for Sunday and Monday is 55/30 & 53/33 F, sunny.

I'm inclined to put some heat on in the RV, and open drawers and doors so the plumbing can get some warm air circulated to it. That was adequate for a trailer with exposed water tank, under the same conditions, so it should be adequate for the motorhome. Any reason it wouldn't be?

The furnace is basic unducted. I'm assuming no heated air is directed under the bed, towards the water tank and pump. Is that correct?

Coolmom, I have been doing this for years without any problems. I use a small electric heater on in the RV set to come on around 50-55 degrees F. Never a problem. I might get concerned if temps get down below 25 or so.....but that is rare on the Oregon coast.... and I would just turn the heat inside up higher.....or maybe drain the water system.

I'm pretty sure that's adequate. Just not familiar with this tank arrangement!

We have a long string of milder weather and I'm hoping to make a quick trip before it goes away!

No worries in those temps.

Thirty is my “concerned” point but that’s your low. IMO you’ll be fine. Do you have an outside shower? How exposed are your drains?

With plumbing in the insulated envelope of the RV, an overnight low around 30 is nothing at all to worry about. The interior of the RV is not going to be below freezing at any point. It's most likely not worrysome even if your plumbing is all exposed. I doubt you'd get anything more than a thin layer of ice on the dog's water dish, if anything at all.

That's what I thought. All the plumbing is inside, with the water pump and tank in the space between the elevated bed/bath and the floor.
Then the plumbing comes up and runs to the bathroom and kitchen.
Thanks!

It takes a hard freeze to affect the plumbing in my trailer. An overnight low of 30 isn't low enuf to cause a problem.
