Welcome to iRV2 .
For first timers , I always say rent a unit for a week or so , drive it around and stay in a park .
As you're in a unit you can develop a list of , must have items you want in your own coach ; then would be nice items, and not really necessary .
So you have a really good idea when you do go shopping .
Also RV life style is not for everyone , so a trial before shelling out $$$$$$ is a good idea.
