If you have a good amount of time before you will purchase/tour--suggest you start monitoring the following RV sales sites:
AutoTraderonline.com for a truck
Often, a truck/trailer combo will be up for sale.
By watching these ads, you can establish the asking prices for various brands/models.
Also suggest you spend time with wife going thru new/used units for sale nearby to get an idea what fits your needs.
Welcome to the forum, ask away on any other questions.
