Tried looking for the coach plumbing schematics in hopes of finding a hot water valve that maybe part way closed (no luck). Plenty of volume on the cold side and no volume or leak issues anywhere thru out the rest of the coach plumbing.Has anyone had this issue.

I had a similar issue with the kitchen faucet. Hot side seemed to be clogged with mineral deposits. Replaced the faucet, problem solved. You could try swapping the hot and cold supply lines to the faucet under the sink to see if you get cold water out the hot side. That would help isolate the problem.

Sounds very similar to the problem I previously encountered with my '03. There is a check valve on the output of the hot water tank. The spring keeper piece had broken which allows the plunger valve to actually try to close from the water pressure. I removed the pieces I found after removing the valve and re-installed the outer brass shell. I left it that way for a couple of years until the water heater sprung a leak and had to be replaced. Your other obvious choice is to replace the check valve.

The only time the check valve becomes important is when you winterize with that RV winterizing solution. I always blew my water system out with air so it didn't matter.

Do you have water volume at the kitchen sink?

Yes Dave,I have very good volume and pressure everywhere else, shower,kitchen and outside utility.I was hoping to find a valve so I can isolate the line and do a back flush.I have never herd of a cartridge failing this way.

Not sure how the sink faucet works, but the shower valve in the 2005’s has a ball with holes that regulates the temperature and volume. The stick that changes the position had broken off. The parts are available at many hardware stores. I would take the valve apart and see how it looks.

Is there adequate water pressure at the end of the hot water supply line where it connects to the bathroom sink faucet?

If yes, then the problem is the faucet.
If no , then there is some sort of blockage between the end of that line and the point where it connects to the hot water line that feeds the shower.

Just want to pass along my fix of low hot water volume at bath faucet.I removed the faucet water aerator then with my thumb covering the faucet outlet I ran the cold water side and placed the faucet handle to the center forcing the good volume side to the low volume side.This forced a small amount of scale to dislodge. After a small shower for me I have good hot water volume once again.
