In my 5er I have two GC-2 batteries in series. It has been a good and necessary upgrade for us.
We have a Honda 3000 watt inverter generator. We have a single roof air and can run it and everything else in the trailer with no problem.
I have heard a lot of good things about the Champion generators but I have to plug the Honda's reliability and longevity. I have had mine for 12 years and I cannot even guess how many hours it has on it.
We lived off grid for a while and ran it 12-16 hours a day. Then we got utility power and became dependant. So, when the power went out we ran the generator hard 24/7. Our power outages were frequent in the Winter and lasted as long as 11 days.
I am amazed at how reliable it has been. Oil, air filter and spark plug changes and one carb rebuild. It's still running strong.
