Semper Fi! Thank you for your service. Make sure you have national medical insurance rather than an HMO. If you are using the VA, you can't go to any VA facility if it's out of the "region" - you're not in the computer! You can however go to any emergency room and they can get pre approval to treat you. My husband is a former Marine Vietnam Vet. W used to travel for 4 months at a time and came to our home base in Florida to see our doctors and get our prescriptions filled enough to last 3 months. We have a DP Class A, stayed at our home base about 2 months then hit the road again. We have been at home base since October because he had open heart triple bypass surgery January 13. He has done very well. We are leaving mid July for our first trip post op. We plan on driving 2-3 hours a day and staying put for 2 or 3 days for him to rest before we travel again. When we went full timing people thought we were crazy. We asked ourselves "what is the worst thing that could happen?" and if we could handle that we'd be OK. Even without medical issues people have emergencies on the road. I agree you should have an exit plan just in case. When we can't RV anymore, our plan is to rent a small apartment near our kids. As my husband said, I know my limits. God Bless you both and see you down the road!
