Because you are in Texas and because you have medical issues, I highly suggest you check out
Escapees. The main location is Livingston, Texas and they offer
CARE(Continuing Assistance for Retired Escapees), an excellent program that helps when the need arises. They also have programs like SmartWeigh that makes sure your truck and 5er are a good match. Because Escapees has been around for years and works primarily with full timers and retirees, they can help answer any questions you might have. It is a great organization/club and worth a look/see. Best wishes to you and your future plans.
