Welcome to the forum and congratulations on the upcoming changes in your lifestyle!
I'm sure you'll get plenty of advice on the type of unit. We went with a 40' diesel pusher as our first RV and we've loved it. However, we don't lug around the toys you're going to need. Just a Ford Explorer toad and two bikes.
We loved the floor plans available in fifth wheels but just couldn't get past the fact that our everyday "car" would have to be a giant truck.
Best of luck.
