OK finally had my first "breakdown"--today on the way to the campground--left-back ,inside tire shredded--pulled over in a parking lot--called Good Sam--quick response-good service--bill was $150--Good Sam paid, I just signed-glad I had a spare-but did leave a good tip. Bad news is, when the tire shredded--it tore loose the tire guard, tire flap, and some small wires, and drain lines for? shower/sink--got to the campground-hooked up water turned it on--and water poured out onto tires from exposed drain lines---Vince--gonna buy all new tires now-dont trust any of them-what do you recommend--and ?price--they are 16"s-6 of them E rated
