The only bizarre problem I had with GS road side service was a blow out and they came out to put the spare on. I figured I didn't need to stand there and watch him so I went for a cup of coffee at the truck stop.
Came back, work done. I had a round tire on the MH so I "thought" all was well. signed the paper and pulled the MH around for some gas.
Got out to fill it up and noticed the dreaded blue stuff running from under the coach. I opened my bay and it looked like a spaghetti war. All my valves and pipes were twisted and shredded.
Apparently the blown tire had gone thru the side of the sewage bay destroying everything including the side and floor of the bay itself.
There was no way the service guy replacing my tire could have missed that when he was under the wheel well. You'd think he could have told me!
