Amount of use does have a large effect on the cost picture. Within the past year we have used our trailer over 130 days and towed over 8000 miles. For fuel I used 12 mpg towing vs 24 if not towing costing fuel at $3.90/gal. We averaged lees than that for fuel and also campsites were less than $40 averaged.
I am attempting to compare similar travel. Flying to resorts in the Carribean is a different travel experience.
I find the cost comparison as follows:
Accommodation RV at $40/night 5200 Hotel at $100/night 13000
Meals RV. 20/day 2600 Hotel $60/day 7800
Fuel RV 2600 Hotel 1300
Totals RV 10400 Hotel 22100
Difference RV Travel less 11700 That is quite a bit!
Yes the trailer did cost $25000 last spring. It has proved economical so far with the amount of use and travelling we are doing.
