Congrats Craig! I am certain you will love yours as much as we do.
I wish I had also gone with the second battery on purchase. I am now looking into doing that myself. I am also looking into an inverter so we can boondock (we are going to Kings Canyon and Yosemite in late April before we report to Yellowstone). I am an amateur electrician comfortable with house wiring but less comfortable wiring in this inverter. I am reading a book "Managing 12 volts" now.
Thanks for the good info on the generator. I do have the bypass switch and a hard wired 50 amp surge guard.
Did they mount the solar panel on the roof (or is it on a movable wire)?
We just took jobs in Yellowstone this summer and the 8289WS should provide a great living space for us. We will be in Canyon Village so if you are there just look for the RV that looks like yours and stop by
