You are embarking on a wonderful journey. Here are some suggestions.
1. Figure out what kind of camping you like to do or envision - resorts, state parks, forest service, boondocking.
2. Explore - see what others do, talk with RV owners, visit RV shows, walk around campgrounds and observe. Campers are friendly people.
3. Decide on brands and models and floor plans that you like.
4. Map out your price range - what you can afford or debt you can live with. Sometimes it is better to buy a little older coach to stay in your price range and get what you want.
5. Make sure mama is happy with the choice!
6. Find what will meet your needs, buy it, and enter the world of RVing.
We were tent campers for 35 years. We like to do USFS and state park campsites. We discovered Monaco Safari Treks with the bed in the ceiling that comes down at night and disappears in the daytime. We enjoy a 29 ft. coach with the living space of a 38 foot coach with a large bathroom. This is a quality coach in a small package. Why tow 9' of bedroom that you only use at night?
If you can live with the bed, a Trek is wonderful! Check out Trek Tracks website.
We found our Trek in Iowa on the internet. Our first journey was driving it back to Oregon. Happy travels and hope you find the unit that meets your needs.
