Moving the mix valve would be a very smart idea. Also having shutoff valves and union fittings so it could be easily replaced / rebuilt. I'm going to have to head to the store and grab come more copper this morning. I realized after i got everything back together i forgot to install the hold backet so a bunch og it has to come apart again this morning to install it.
Yesterday all the shut off valves i ordered showed up so i reassembled the pluming on the Aqua-Hot. Before i did i needed to change some fittings so i could use the shutoff valves.    
I removed all the female fittings and installed male ends so i could attach the shut off valves

Here's how i ended the day

This morning i was going to get started on wiring everything back up.
   
Now I'm going to tear things apart again and move the mix valve and install the hold bracket i forgot.
For those wondering I'm a big fan of shut off valves. They save time and cleanup. I use them on anything i can, including... the tops of air bags. If one of the drive bags blows out just crawl under it and close that bag. Wait a few minutes and the remaining bags will lift you off your tires so you can continue to roll to a safer location or where it can be properly fixed. I crawled under my coach the other day looking to get a bellows number and realized all mine are plumbed with massive 1 inch line, a blown bag will drop things fast! That's going to be my next major project, replumb the air system with 3/8 line and push fittings.
