Be sure to check with your camp ground what hours the generator is allowed to be used. Alot of COLO sites still have generator run time restrictions in place. Most public places do not allow generators after 10PM and before 8AM the next morning.
We use 255AH Battery setup and do rather well well making it through the one day/nite run off the batteries. This runs our battery bank down to around 50% charge state and require us to run our generator using smart mode charging for at least three hours at 8AM if allowed by the camp ground.
The VENTED TYPE CAT WAVE Heaters do pretty good mounted to a trailer cabinet door and vented to the outside. There are some photos on GOOGLE SEARCH showing one installed this way...
The general rule of thumb for the RV FURNACE setup is one night one battery. The killer is the loud 12VDC FAN which draws 6-8AMPS DC Current. We pretty much run the same things we run at electric sites except the Air Conditioner and our 255AH battery capacity does ok. This is usually not using the Rv FURNACE for heat however. My backup for heat when OFF-ROAD is a MR BUDDY Heater but you have to provide good venting which lets all your heat generated escape out...
Adding SOLAR PANELS to my setup would do great still requiring the generator use to get past the initial high current battery demand of around 53 AMPS DC CHARGE current. After an hour of generator use then the DC CURRENT demand will be around 6-8AMPS DC which would fall right into the solar panel DC CURRENT OUTPUTS during the high sun periods.
We like running the generator first thing in the mornings as this is when we get to make our good fresh ground bean coffee for the day.
All of it takes planning.
