Winter RVing in a Class C

How cold are we talking? I've successfully been in -37 C (-34 f) but I've made a LOT of modifications to be able to do so.

Are your waste tanks enclosed?

There is a wonderful sticky thread on winter camping under the full time forum.

You may need to add some heat to the exterior of the fridge.

I am able to heat electrically at campgrounds that have 50 amp service. I'm also able to do so if I have access to three 15 shore power outlets (on different breakers, of course).

Do NOT use an unvented combustion heater.

We live near a ski mountain and want to camp with our 23' Class C on weekends at the mountain. So, how do I eep things from freezing both while camping and while stored ( outdoor covered - with power). My initial thoughts, which could be way off are as follows:

Tank heaters for fresh, gray and black tanks.
Cargo heater in cargo space near valves and pipes
Small electric Heater inside near sink and bathroom.

These would all need to be DC and running when in storage or camping. FYI, there are no hookups at the mountain so I will need to hook up an external generator to keep batteries charged and run appliances.

I need details as to why this might not work or specifically what products I should use etc. the more information the better.

Thanks!
