2002, I did a spreadsheet comparing Hotel, car/airfare vs Truck & RV...... I was in Virginia at the time. It is old pricing, but I do love to throw my thoughts into a spreadsheet, from time to time........
---Trips over 500 miles, started showing a larger difference in plane & hotel vs RV configuration. So more long trips increased the savings as compared to airplane/hotel costs.
---Operating costs are not considered. It is in the airplane/Hotel pricing, but not in my RV configuration. Looking at new vs Used, I figured I would get the lowest costs (The best years) out of a new rig. I also noticed, that if taken care of, the bottom value after 5 years, is half of what I spent for new (Looking at used 5 year old rigs)
---I paid cash, so I paid what it was worth with no interest to factor in.
Maybe some day, I will re-visit my guess before I owned an RV and see how close I got...I am tracking all my expenses. Notice, that large 5th wheels were only 60K back then...LOL
