You also should consider where you may be using your generators. This is really a big problem for alot of of campers. On the east side of the US most public camp grounds including the Natl Forest sites all seem to have generator run time restrictions in place. Most we see here on the East side of the US is from 8AM-10AM in the mornings and then again from 4:30PM to 7:30PM. Never see anywhere that allows the generator to run in the evening hours let alone all night long. Most East side Natl Forest areas have the short hours as well and some may allow from 8AM to 8PM. Out west you have alot of dispersed camping where you can do whatever you want I guess.
I see everyone wants to have the generator to run the air conditioners but it amazes me where they think they can run them at public campgrounds. Just doesn't happen where we go camping...
With all of this in mind I decided very quick my best solution was to give up on running the Air Conditioners and high wattage appliances when camping off the power grids and beef-up my trailer to run all the 120VAC things we want to have running from the an Inverter and a very large battery battery bank. The only reason I have my 2KW Honda Generator is to re-charge my battery bank in a quick three hour generator run time every morning starting at 8AM using smart mode charging technology. Once I get the batteries back up to their 90% charge state then we can do it all over again for the next day/night run off the batteries. The saving grace for me was getting a good smart mode converter/charger going and changing all my automotive lights over to LEDs. Also installing at least a 220AH Battery bank would be a must do situation.
