Welcome to CRLV
Do you know if you intend to do much driving ?
Long road trips full time to see major sites "Tourist" "Camping 1"
Travel some in your own area and stay a month here and a month there. "Seasonal Campers or Boondockers". "Camping 2"
Or there is the third option most people know as "snowbirds". where you travel a considerable distance for a more southern climate during the winter, before returning back to the more northern base in spring. "Camping 3"
As a kid I used to listen to my Dad describe this to his friends. He traveled in his work and finally just chose a Van for himself. But this evaluation technique helped him better choose between types of Vehicles within cost budget/benefit considerations. He had a Class C RV for awhile and finally just chose Vans.
You may find small Schoolie's for sale already converted. Some people are making a hobby of building these now days when they find two or three of them cheap enough to make it profitable. With a bare Schoolie there will be some real work involved and expense. I know of a couple of brothers who do this between jobs.
One is a House Framer carpenter and the other a Cabinet installer. One may be wise to consider a starter vehicle such as a good deal on an old used Winnebago Brave that is in good condition as a Class A or a used Class C which is the RV built on a Van chassis. These often show up when a full timer couple retire from it suddenly due to health or other reasons etc. Some are estate sales, and were in use up until that time.
It may cost a bit more up front but you gain the advantage of going on the road that same season where with a bare schoolie you may spend the first season just building it out and getting it road ready.
If you choose the RV route you may want to know what the current used prices are on the different models.
Most RV Lots purchase the NADA RV guide but they aren't into sharing the info in them too freely. You could purchase a used one but they aren't too common.
This way you would know the stated values. Then you need to know the service history, break down & repairs made to it etc to be able to offer a good faith proposition when dealing with another private party.
Often people just go on the Bank Loan Value as a basis and deal from there.
A built out Schoolie is a unique vehicle, almost a one of a kind, and there is no real way of putting a value on it.
Occasionally I see some real beauties here in the Ohio Valley where I live between Pittsburgh and Cincinnati. They are built for University Sports Alumni types who like to travel to Home Coming events etc or Snow Birds
who will drive to Florida for the winter and then return. "Camping 3" types. Most of these Schoolies will probably have 25 to 35K of good miles on them. Which for those in my area would translate to 3 to 5 years of Snowbirding before they find a deal on a Florida Home or Condo and sell the Schoolie.
So I offer you this as a way to evaluate some of your needs or desires beyond your choices of vehicles. It may help you choose better. If you buy a used RV, the first season you may try the "Camping 2" method to learn what it is like and know what would appeal to you. It will also keep you close to home in the RV so you
can test it out and evaluate if for an extended road trip of touring or for winter snowbird camping.
All the best.
