This question has all types of answers so I might as well add mine.
At -23 degrees things do get hard.
I need to know what is the temperature mid day?
How long of a very cold spell does the weather forecaster predict?
My answer with the limited information.
If your MH cooling systems has proper antifreeze and this cold snap is only a few nights and day warms up to 10 degrees above zero or more, no problem.
If you were to leave your MH for a few weeks in sub zero temps and have weak batteries I can see a problem starting back up.
Oil and antifreeze will get thicker only in prolonged sub -zero weather.
For short term no problem.
But when you are ready to drive off you need to warm it up. I would insure you warm up the transmission by putting in neutral during warm-up. And move it thru the different positions before you drive off. This will insure ATF is warm and flowing well thru the valve body and torque convertor.
Everything should be warmed up within 10-15 minutes.
OK that is all I have to offer.
