Your grey tank would be far safer and less likely to freeze if you put it inside of the bus.
Unfortunately, getting your shower to drain could present an issue. That whole gravity thing......
Also, solar production is likely to be somewhat limited if you are in a climate where it is cold enough to worry about freezing.
When I was full time in cold climates in would pour some RV antifreeze in the grey tank after dumping.
Worked for me in Minneapolis in February.
