Jason, Welcome to the forum.
There is a RV show coming up the end of the month in Edison. It is a good place to compare all makes and models for floor-plans that will fit your family. Leave your checkbook and credit cards home ..... You are just there to look
and find a floor plan that works for you. Since you are looking to buy used, do some homework on local dealers that will be able to service or supply parts for whatever you buy. A good dealer is very important to making you happy with your purchase.
While at a show get all the brochures you can carry so you can compare makes and models at home. (Most manufacturers have them available on line too)
As for the WD hitch .... yes, you should have one for any TT you tow. They make towing safer and more enjoyable.
