What I can contribute is that you can get from ND to my latitude in a day...I would not go crazy with water where we are, but our average weather would probably be safe for cats even if the worst happened and your heater kicked off the moment you left.
As everyone has said- watch the weather and be smart and have full LP tanks- but I see that you are from ND so you are probably smarter at driving in weather than most of us.
Finally- as I considered your question- in my shoes, I would rough it for those two days...perhaps forego a shower- just wipe down with a wash cloth using water jugs, etc. I would not fear using the bathroom...as others have said, use minimal water from jugs and maybe have some anti freeze in the tanks.
I also noted this post below and have two very different reactions to it. My first reaction was "no don't listen to this worry wart"- your camper will serve you just fine- perhaps even better if you get stranded briefly somewhere. However, my second reaction is that saying to heck with the camper and sleeping in a motel is certainly the easy way out and I wouldn't hesitate to do that if I just had to have a long hot shower, sink, etc...But it's your choice.
My bottom line is that by the end of day 2, you can probably start using the camper to near 100% of it's capability, as opposed to 80% of it's capability before...pretty much everything but running water beforehand.

Remember that IF you don't put any water in the water tank and IF you don't use the toilet and IF you don't pour anything down the sinks, then you don't need to run your furnace during the day. I'm still trying to convince you to not use the coach until you're below the frost line - just do the motel thing while traveling - but make sure the rig is winterized when you take delivery. My favorite word is 'simple'.
