The benefit of crank out windows is they can be opened in the rain. The slide windows, not so much. I find it aggravating, not having at least one crank window for air, but what can you do?
As for leveling jacks, sometimes I miss my tt. It was much easier to level front to back. Or it could be the campgrounds I have been staying in. But, push button leveling jacks, when you are on fairly level ground, make set up a lot easier. And, they keep the fridge level. Get jacks.
One of the reasons we ended up with a A instead of a C was the step up from the cab. The cab feels like a cave after being in an A and the space is pretty unusable while camping. However, if we were going to go shorter (less than 30') we would definitely get a C, step up or not.
Rapid camp sounds like a stupid gimmick. I rarely want to start my generator when I arrive, considering the batteries are usually fully charged from the drive. Often it is too windy for my awning, and I only have 3 buttons to push for my slides and jacks. Is that so hard? Is there an option not to 'rapid camp?'
