It’s going to dip to -1C tonight, but the kids have persuaded me that they cannot wait until it gets warmer to try sleeping out in the California. We used the levelling system and some chocks (easier than I expected) to deal with the hill outside the house. Warmed it up for 15 minutes with the auxiliary heater (will be interested to see how much diesel that uses). Put the blinds up/down - impressed with the magnetic ones, as the sucker cups we had for our Bongo were hopeless. The kids are sleeping happily upstairs (for now!) and I am trying out downstairs (less comfy but maybe a little warmer). Just hoping that their bladders last the night - I may regret not laying out for a portapotti!
