I have a small motorhome (Roadtrek), gets about 11-13 mpg loaded, full tanks, all gear. With chains, drove it in some tough New Mexico weather and it was scary but do-able.
However, I agree, it would be 25+ miles away if caught at work when the bad things happened.

Another plus- it has a nice Onan generator, so I can use it to power refrigeration and re-charge necessary items until power is restored, it, of course, uses the main fuel tank so 30+ gallons until the tank level falls below the generator feed line. I estimate 5 days? of intermittent use........

And an okay ac/dc/propane fridge, and a propane tank for it's little water heater, etc.
