Well....actually....we full-timed for five years in a 40-foot diesel. So I do pretty well know my way around. But I've never encountered the problems I've seen with this coach. With just 6 hours on the gen, and 22,000 miles total, I wonder if some of the problems are just from sitting too long, and that some things need to be exercised, some things replaced, and some things I just need to read the manual and figure out how to use!
I did check the outside shower. With the valves open and water spraying, the swivel-thing on the back of the shower head seems to do nothing at all, so I can't tell if it's "on" or "Off". But, the hot and cold water valves are definitely off.
