I guess you have checked out what to expect running the generator at public camp grounds... I always run into all kinds of different restrictions running a generator on-site...
I suspect your 4400WATT Generator is going to be one of those contractor $400-$500 type generators which is going to be very loud when being used.
Some restriction run times were 8AM to 10AM and then again from 4PM to 8PM that evening. Other places were 8AM to 8PM... No where did I ever find you could run a generator at the public camp grounds between 8PM at night and 8Am the next morning.
Usually camping at Dispersed camping location mainly out West you can run the generator anytime you want to. Not many dispersed camping locations here on the East side the US...
Of course on private property it is up to the grounds owner when it is allowed...
This made me beef-up my battery bank, upgraded to smart mode charging, and replace all 12VDC light to LEDs... Having the battery bank large enough to satisfy our appliances we wanted to be able to run including the Home Entertainment so that the battery bank would not get below the 50% charge state until 8AM the next morning. Then we could run the generator with the shore power power cable connected to recharge the batteries back up to their 90% charge state in a three hour run period so we can do all of this all over again the next day/night off the batteries.
In my case this did not include Air Conditioning or High Wattage Microwave etc...
For me adding solar panels just reduced the amount of time I would have to run the generator when first starting the re-charge cycle when high DC currents are involved... Once the DC Currents tapered down then you could just let the high sun charge the batteries will you are in high sun.
This is what I went through to be able to camp OFF-GRID with my OFF-ROAD POPUP trailer setup...
Having the larger motorhome or large RV trailers is a different situation I reckon... I do know I have been to several camp grounds and hear the big motorhomes and Class A running their generator whenever they wanted to. I guess there may be a double standard here haha... having built-in generator probably hides the fact pretty good... Is the diesel motor running or the generator perhaps haha...
Just some things to think about before dumping bunch of monies into the project...
Everyone wants to install their generators haha...
