Welcome. I am sure you will find the answers you seek here. A few general comments.
1. Trust the information provided here before the dealer. Members have no incentive to sell one unit over another as the salesman does. ( Your tow vehicle will not tow anything on their lot).
2. Take your time. Most people starting out go too small and trade up shortly after ( usually results in lost money).
3. Make the decision process a combination of RV and tow vehicle ( if trailer) as they are very closely related. If possible err on the high side on the tv as it will usually outlive one or two tt.
4. Don't sign paperwork until you have done a thorough walk thru and everything works.
5. Ask questions .
You are buying this to enjoy, make the purchasing process enjoyable as well.
