I've never wanted to take a Thetford out with us, we use on site facilities, but that Bivvy loo only takes the space of a couple of bottles of vino, and what with advancing years these nocturnal emergencies could soon be a thing! Very impressed in the video by the talented young guy jumping on the toilet seat, I would probably break an ankle in the process I'm sure. What a neat solution, with no solutions!have the sam for emergencies - I recommend the bag in a bag technique.
first in - a bin bag to cover everything, second in is the waste bag. then at least you know the throne stays 100% clean!
