What area are you finding the antifreeze? Is it inside under the dash ? Under the coach?

Or electric heat and the genny if the fuernace does not work.

Alas, this is NOT a good suggestion, since it does not allow you to direct warm air to the defroster vents.

But it is how I had to do it on a car, thankfully in the summer, a couple of times.

(In days of old removing the heater core on a car was simple.. Do as above with the hoses, pull about a dozen screws, lift a lid and there you were.. Today... Evacuate air conditioner, disconnect and seal lines, Dissassamble half the dash, on one model car you pull the steering column, THEN you can slide the A/C evaporator out on it's rails and lift the heater core out from behind that. ) (Never done a modern one).
On a ford ranger pickup 2000 year model the core costs less than 100.00 with labor to have ford do it is over a 1000.00. My friend and I replaced the one in my sons truck for him. We had to completely unhook the dash and move it up with some twisting and pulling we managed to get the dash far enough up to replace the heater core. It is ridiculous. they could cut a opening in the fire wall install the dash and then put a cover over the rest of the opening. Would make it a 1 hour job.

It's a little different when the outside air is below freezing. Any moisture inside condenses on the inside of the windshield and if the OAT is low enough the moisture freezes.

Anyway you look at it, replacing or having replaced a radiator or a heater core on an RV isn't a quick in and out thing.
