I live in a 31’ Jayco with 16’ slide out. I heat with a pellet stove, and run propane for running my fridge and hot water heater for showering. I only run the hot water for that purpose. For general hot water I keep an SS pot on the stove for ready available hot water for general use.
For power on the RV I run 400 dollar 5 kW inverter from Harbor Freight. I was a little Leary of the HF unit, but after 2 months it has not gave me a lick of issues. I have 4 heavy duty lead acid batteries in parallel. I am running the Predator 8750 generator with an auto start and shut off system for charging the batteries. Im using a PowerMax 100 amp charger that is plugged into the genny. Right now I am running on gasoline, until I can build a new gasifier unit.
If you run on wood gas and need the 30 amps than you will need the equivalent of the 8750.
I will be working on a new micro gasifier for 2019 that will feature full automation for the 3500 inverter generator. With the battery bank and the 100 amp charger this should be easily doable with this smaller generator and it will be more efficient. This will run on pellet fuels; for me making chips is more work than its worth. Id rather pay 4 bucks for a bag of fuel vs working over an hours time for the same amount of energy producing chips.

3500 watt genny with electric start.
5000 watt inverter
If you can afford the inverter it will be very big cost savings to you. It will cut your fuel consumption in half at least. With the inverter generator and the 100 amp charger I bet you will only go though 2 gallons of gas a day maybe even less. The 8750 goes through roughly 3 gallons a day and its twice the engine as this 3500 watt gen. Plus the 3500 watt is very quiet.
I can offer the auto-start system if you would be interested I am planning to bring this to market for existing gasoline back up generators. The Flex Mini Gasifier that I am planning to build with have this feature built into it.
Edit: The 8750 will run for four days on 5 gallons of fuel. So its averaging, 1.25 gallons a day!! So that 3500 watt genny will be interesting to see how much more efficient it is.
