Not to me — gas savings not worth it. Not even close.
I burn close to 50 gallons driving to game and back each weekend. The difference in generator fuel is less than 1 gallon in 10 hours of running A/C overnight (2 versus 1.3 gallons). Even if twice that, it doesn’t show up on my radar. I’m just not going to worry about $2 of gas when I’m spending hundreds on other costs.
By the way, I recall you got pissed last time I brought this up, but if you believe manufacturers data, people who own a diesel inverter generator like yours can run a couple of A/Cs (or just one) with same or less fuel than portable generators. You’d have to be down to almost no power at all before portable saves a tiny amount — certainly not enough I’d worry about.
Not running the diesel for other reasons, like making it last longer or having a backup, is a different issue. Fuel savings alone is insignificant.
At games I’ve noticed only those without built-in generators use portables — mostly a few trailers. Motorhomes all run their Onans.
