Welcome to the forum and congrats on your upcoming changes! You'll have a ball.
What type of RV to buy is a big question. Although gross generalizations:
1) Class A coaches are much more popular for full timers than Class C because of the living area they provide and storage room... not to mention how nice it is to view the scenery through those big picture windows while sitting way up high.
2) Coach owners like the idea of being able to access all of their living space without having to get out of the rig and walk back to the trailer. Some even see it as a safety/security plus.
3) Fifth wheels are more popular with folks who tend to stay put more than they travel and coaches are more popular for those who do a lot of travel.
If you do decide on a Class A then you have to decide gas vs diesel and nobody here on the forum has an opinion on that.....
Best of luck to you. Stay in touch and feel free to keep picking our brains.
