I don't plan on using the B Van during the winters as I have another larger RV that's connected to shore power 24/7 year around.
I'm currently stay full time down in Northwest along the Pacific Ocean where temperatures are relatively mild, rarely drop into the teens during the winter months.
There's alot of humidity and it rains alot but doesn't really get very cold, especially if your located near water such as Pacific Ocean, Puget Sound, etc.
Yes, its would be a big hassle and expense to install a black water tank using a macerater. So I'll probably pick up a Dometic or Thetford 5 gallon porta potti or build my own toilet. There is an article online of some people converting a Thetford Porta Potti into a compost toilet.
How to turn a chemical toilet into a composting toilet
May 31, 2016 / VanSpecies I've found a few new Dometic 966 series on eBay for under a $100.00.
e.g. https://www.ebay.com/itm/253056969380
I'm uncertain how the the Dometic and Thetford Porta Potties compare to less expensive units ~$50. to $~65.00.

But from reading reviews their not all that well made, some care needs to be taken not to break them. Porta potties potentially have problems with leaking if not handled correctly.
I'm thinking of looking into perhaps a home made composte toilet. Trying to purchase a compost toilet for an RV potentially can run from a grand to over two grand. I saw a less expensive one for around ~700.00.
