I have 6 dogs and 4 cats and 6 foster cats. If I have to evacuate due to a hurricane, I need my RV to transport all the animals.
I also find it much easier to control my diet if I eat in my RV, vice restaurants.
I sleep better in my RV than I do in hotels.
I've travelled a lot for work and I'm forced to stay in hotels most of the time. There have been a lot of times when problems at the hotel have made them less than acceptable. One trip to North Carolina, everyone but me ended up with bed bugs. One trip to West Palm Beach FL the fire alarms sounded a dozen times during the night.
I've had more problems with drunks and kids wandering the hallways and yelling at 1 a.m. than I wish to recall.
If I fly somewhere I end up renting a car. By the time you add up the cost of the car, the airfare, the hotel, and the restaurants you've paid more than you would for driving your RV. I used a spreadsheet to calculate the costs of driving and staying in a hotel, flying and renting a car and hotel, and taking my RV. It varies depending on fuel costs, distance, and length of stay, but there is a breakeven point where I calculate it's cheaper to take the RV than to fly.
