Wen 3600 gas consumption?

[Hoginedgewood]

I have had the truck camper 2 years, this is my first primitive camping experience. It’s a when 3600 and I have 4 gallons left. Wondering how many hours I get on a tank of gas. I think it’s about 1.5 gallon tank.

Wen generator not when.
I was getting about 5 hours a tank, seems like about 1.5 gallon tank.
And that's on eco mode, which is annoying when the coffee maker cycles
