I'm surprised it didn't sell based on that. 20 years ago when I was in construction the truck drove at most 130 miles per day (we made sure to work 14 hour days when we were going to spend an hour on the road - the crew hated those jobs), but typically more like 30. The the first thing we did was pull the generator out of the truck and started it. If would could just plug into the truck that would have saved a lot of space/weight in the truck, it seems like a no-brainer.

Then again, all the construction sites I see these days have mains power on a post, which we never had back then (I don't live in the same state so I don't know if this is universal or just this area has always been different).
