It's different in a B+ for us
We did most of our cooking outside with our B. In the B+ it's probably 50/50.
Breakfast has been indoors in the B+. We use the oven to "toast" bagels etc. We miss the 'camping' we enjoyed in our B and will try to do more of it but we do enjoy the extra space in the B+.
When dry camping we used to wash dishes outside often, using water from campground taps and draining the water in the campground drains. We used to use campground showers whenever possible. Now we only shower in the RV.
Consequently, we're using more of 'our' water and filling 'our' grey tank!
We're using more propane too with the oven and larger fridge.
The transition from B to B+ has been straight forward. The B was easier to drive. The B+ is much wider & fills the lane.
