Good for you, ClayI bought a walker last week on Amazon. Some days I need it, others I don't but I've taken a few falls the last year.
If you want the motothome, go for it. Get what works for you.
When we got our first RV, my Aunt was constantly telling us why we didn't want what we wanted and should get such and such. Finally told her, "what works for you, will not work for us."
Absolutely, find that barely used 2-3 year old. Save the $$$. The economy will drop those new prices, too. RV shows will start up in Feb. Last day of show is a great time to get a deal.
Hope everything works out for you. Enjoy the adventure.
