Low hot water pressure

My latest issue....
I have a higher water pressure on the cold side versus the hot water side. This is the same for every water fixture in the coach. This isn't a major issue for the faucets but is a problem in the shower.

In the shower, I get fairly strong water pressure when on cold only but as you increase the hot water to a comfortable temperature, the pressure drops to something that barely resembles a "shower".

I did have the mixing valve replaced on the Aqua Hot. Somethings tells me the mix is hot/cold mix not the issue though. This has to do with volume. Any thoughts on what could be restricting the hot water flow?

Fred,

It cold be calcium buildup. When the mixing valve was replaced was it full of calcium?  Have you acid washed your system with vinegar lately? The hot side always percolates calcium out more than the cold side at the brass PEX fittings.
