Thanks, I'll check out the TST system. I've seen that recommended in other posts as well. It'll definitely be one on board before my next trip!
Update on collateral damages following the blowout.... the shower drain took a hit through the floor (it sits directly over the tire that blewout). The plastic flange that connects the floor drain to the shower floor broke and along with the rubber gasket were laying in the shower floor. Now I gotta figure out how to access underneath the shower to find out if it cracked the drain pipe/trap. Any ideas how to access that? There's a removable panel in the bedroom behind the shower knobs to access that plumbing, but I doubt that there's enough room to get underneath the shower floor. Would there be another panel that I haven't seen yet or is it only accessible from underneath the coach?
