Please call Midwest Sales about the Apollo. Their number is on the left side of the Portal. Jm...Our other problem is the Apollo microwave/oven which seems to have a mind of its own... turns the oven on in the middle of the night. So, for now it's unplugged. We'll ask that question in the right forum.
Welcome! Yes, the second air is worth it. These units are too big for just one for adequate cooling. We also added a hard wired surge protector and Trav'ler satellite dish - love it.
Ours came with a satellite dish, but I believe it is only regular satellite, not HD. I'm going to look into it more soon. I like the idea of a hard-wire surge protector.
One thing to remember on the hard wired is that when using an external generator (we use a Honda eu2000 which is detected as having an open ground), it won't allow the power from it in, so we had to make a bypass unit. The hard wired works great though with shore power.
