Thanks for all the great replies. I'm not really interested in getting ANOTHER vehicle.. I think I probably have enough toys as it is. Also i'm not interested in parking my RV at a bugout location.. I still use it for camping all through the year..
Maintenance on both vehicles is up to date. Oil changed every 3000 miles, fluids and filters checked, tire pressure, etc.... Both vehicles have less than 20,000 miles on them.
I think the best bet would be to try and take both vehicles. That way I have the needed shelter for longer term survival, but I also have a getaway/scavenging/exploring vehicle. BUT if I could only take one I think I would try and make it with the RV.. If I could get my bike loaded up in time, that would make it a pretty nice. Especially for supply runs and exploration.
