The average room takes 2 loads of laundry, which would be in the neighborhood of 10kw of electricity. 1 gallon of gas represents the same energy (ignoring losses) as 33kw.

The average 2017 car in the US got 25mpg. So with a 15+mpg difference, you'd need to either drive 5 miles or less per day (0.3g difference), OR average 100 miles per day and have the hotels wash the laundry 20x as much.

There are a lot more costs (both paid and environmental) associated with hotels than just laundry? Staff, lighting, heating. Plus eating out, taxis, and air travel.

Also, retirees roaming around the country in an RV generally sit in one place for a week or two at a time.

Are you not including the air travel component of the travel (which often results in the passenger choosing to travel much farther than a typical RV trip)?

Missing a lot of costs for hotels, also missing the air travel which is the single largest contribution to emissions in this scenario.
