New Mountain High Oxygen System Installed

After some debate in another thread, I decided to install a Mountain High O2 system.
Before getting into details, I want to give a well deserved shout out to the nice folks at MH, located in Redmond Oregon.
Rather than having the unit shipped, I flew from the Bay Area KCCR to Redmond to pick up my installation kit.
We parked right behind their building on the West side of the airport and Brad (the Owner) passed us through the very secure gate.
We had hoped to walk off the airport for a quick lunch before our two and a half hour return trip. Most eateries were 3 or 4 miles away and Brad offered to
drive us there and agreed to pick us up as well after lunch. He asked that I not mention his "uber generosity" in a google review but here on VAF, why not.

The install:
The installation documentation is top notch with detailed engineering drawings and color coded hose arrangements.
All hardware, especially the regulator valve is a beautifully machined work of art. All components I am told, are manufactured here in the US.
Good products aren't cheap and cheap products aren't good. It took me some time to get used to the price as I had hoped to accomplish the same for much less money.
However, after seeing the effort and engineering that went into this product, I fully understand the price tag.
The price for this 4 place kit including all installation hardware and a 682L bottle was just over $2500.
The plan was to install all of the hoses and components behind the baggage bulkhead and overhead console for a neat and clean look.
The bottle is mounted flat in the baggage compartment and is easily removable for refilling.
The system has been pressurized and function checked, so far so good. A label on the left side of the on/off switch will indicate type of bottle and O2 duration guide chart. The 682L provides 15hours of supplemental O2 for 1 person using the MH3 on demand cannulas.
A nice trim piece will cover the bulkhead hose penetration once I am satisfied there are no leaks or issues.

Yes of course it will have a reinforcement doubler with a grommet and a bit more clean up.
The bulkhead is not actually penetrated, just the corrugated cover so I can remove it without removing that unwieldy hose.
I left it loosely in place for pressure testing.
 
Thanks for sharing your O2 installation with all of the pictures. It is helpful for those of us thinking of adding O2.
