2007 Bigfoot 15c9.3...about to pull the trigger...Update

We sure like our Bigfoot, get a good solar setup an forget about the 2nd battery for awhile. I put a second in ours because we were going to Yosemite one winter and I was afraid I may not have enough power to keep warm in the snow with all the power that they are supposed to use, well I think I used the heater 2 times at night before bed and that was it. These campers are really the true 4 season campers.
