I am sure this question has been asked about the Blue Birds, how well
are they for weekend winter sking trips? We are contemplating
purchasing a used Blue Bird. It would sit during the summer on a lot
we have in Canada from May until October. We then would use it over
Thanksgiving going to North Carolina which we have done before in our
previous Motorhome with no freezing problems. We would then
winterize it and store it for the winter. I want to have a Motorhome
that we can drive to the ski slopes and park it in the parking lot
(back out of the way) and spend a couple of nights. This would be in
temps that could go down to sub-zero overnight and during the day.

I have been trying to understand the Primus and Webesco systems.
They seem to work off both the engine heat and the webesco which
seems to be a small furnace that runs off of diesel to heat a boiler?
Will they keep the unit warm enough that the water lines, water tanks
and waste tanks won't freeze?

Next question is how difficult is it to drain the water tank and blow
the lines once I get home until the next trip. Also, where does one
go to drain the waste tank during the winter in places like Michigan
where all of the campgrounds are closed?

Thanks in advance for any answers,
