I would do it for my dog because I want ac to be running all the time should I need to run into the store.
As far as the selection, I think it comes down to the floor plan and price. I need a b with second row captains chair as I will be driving with 3 people. Passenger comfort is not there in a c and they are not always safe. That leaves me basically the winnabego , roadtrek airstream and galleria. Roadtrek is sold out till 2021 and everything is going to be a lot more than the galleria without any super special improvement that is worth the 20k more I need to pay. Lastly you can still get discounts off the galleria , so I think it is down to them barring any special things they come out
