Only the factory will be able to tell you the models that will be installed in a particular unit when the build sheet is signed, but I can tell you what is in my unit which is a 2015 and built in July.
A/C: 13500 BTU, Dometic model 641935CXX1C0, mfg 641935C751C0, prod# 936000724. So far I'm pleased with it's capabilities in the heat. It is loud, but I knew it would be, having experience with this before. I don't love the new style distribution panel, but the only thing I'd like better is probably ducted air, which is not available.
Converter/charger: Parallax, Series 5300. The inverter is Xantrex Pro XM1800.
Water pump: Shurflo 4008 RV Revolution.
My antenna is King Controls, but this is an upgrade that I asked for. The stock antenna was the crank-up, which I didn't want. They would not guarantee reception, as they had not tested a King Control antenna, but I was willing to take my chances and I'm happy with it.
