winter camping advice

Ya, we had really thought we could get a rental but we've had the rug pulled out from under us each time due to it being a very hot rental market (and cats). As that we arent using the water lines the only thing I really need is for the blackwater tank not to freeze. I'm wondering if I should leave valve open for the sewer line or allow it to fill up (with antifreeze mix) then dump

Hello, We need to use a camper in northern Michigan over this winter while we build our home. We are trying to buy an "artic" version and likely wont use the water lines (I'll have jugs of water for flushing the toilet).

Will the onboard furnace be enough to warm the eunit in most cases in winter ? I'm very hesitant to leave my wife/cats alone in the trailer out of fear of a fire. I was wondering if electric baseboard heaters would work as well.

Any advice, experieces would be welcome

Just realize that there are only a few manufacturers that make a true 4-season RV, such as Arctic Fox and Outdoors RV.
Having an "Arctic" package doesn't make it 4-season, only just 3-season at best. These packages are marketing gimmicks that usually only provide heat to the holding tanks. They rarely include increased insulation.
Unfortunately you are behind the 8-ball starting this so late.
