Great list, Bill and Pat! I'd be interested in any ideas for accomplishing #4, though! One might be to check air pressure frequently. Another, for me at least, might be to avoid Goodyear Marathon tires. Or maybe just catch the defects early. On our Montana we've had three of those tires go seriously defective but caught all of them before they blew. On our Jayco Eagle, however, we blew one at highway speeds and were just lucky to have no other damage. So if you have ideas, I sure would like to hear them!!
