What extras should I insist on in a new Class C

We spent 3 hours looking at RVs today after many hours of research and using all of your advice. We really appreciate all the great advice. We are almost sold on one we saw, the 2015 Forrest River Sunseeker 2500TS. It has almost everything that was mentioned except no auto leveling(which I want) and the two phase furnace which we do not need since we are heading South for winter.Thanks again for all the advice.
