Oxygen System
Can anyone recommend a good oxygen system for RV flying out west and needing to go high for crossing various mountainous terrain and how much I can expect to pay?

I use the pulse demand type system, so easy nothing to adjust just use it. I think it's a Mountain High system. I get the tank filled at the local welding shop for $22.

Lots of prior discussion in various threads on VAF. Some ideas on DIY systems, as well as various mfg. Suggest using the search feature of the forum, or use google search on the forum. Way too much to repeat here.

I bought a tank that?s tall enough to see the gauges when it stands on the baggage floor (right side) and mounted to the sidewall. This has worked out very well for me.

I actually made a system for <$200 from new parts available on ebay. Pick a tank size that fits your need and space (170 liter M6 for me), I got a Easy Pulse 5 oxygen conserving regulator, cannula, and a pouch for the whole thing. I purchased some flow spinner things from Mountain High so you can see the oxygen flowing each time you take a breath (sometimes its hard to detect). The whole thing weighs 4.1 lbs and is all medical grade stuff.
The regulator has 5 settings for the amount of O2 per breath or can go continuous. At the highest setting the 170L of O2 last 3.2 hours and 10.1 at the lowest. Set it based on your pulse oximeter. Mounted the whole thing with a fire extinguisher mount.
I get it filled at Roberts Oxygen. They gave me a bit of a hassle the first time, but once they stuck their label on the bottle, it wasn't a problem after that.
Could send photos if you want.

+1 Mountain High
I use the Mountain High O2D2 with one of their smaller cylinders. Easy to operate and even the smaller tank lasts forever.
I get mine filled at the scuba shop for something like $15. I should have gone to them first. The welding place balked, the local FBO is expensive and didn't give me a complete fill, and the medical place demanded that I exchange cylinders. Scuba guy just said "is tomorrow soon enough?"
So easy and cheap, and my usage is so low, that I haven't been able to justify my own O2 filling setup.

Definitely get a pulsed delivery system. The real reason is so that if you're on a trip, you don't have to try to get it refilled when you're out in the sticks.

Hi, Don. I got an RV8 earlier this year and need to fly over the rocks from Seattle to Bozeman to see parents, so have been thinking about this. I am not very handy...is what you have done pretty easy to set up? If so, if you would not mind sending photos / parts list, I'd be so grateful. Leopold@uw.edu would be the easiest way to get it to me, rather than posting here.
Thanks so much.
Seth Leopold

You can buy one of the kits designed for aircraft for hundreds of dollars or you can get what you need off ebay for less than $100.You will need a 165l bottle with post valve and a regulator. You will need a cannula and maybe a pulse oximeter to monitor your oxygen level.
I had a hard time finding someplace to fill my bottles so I bought a 80CF bottle off ebay along with an adaptor to fill my little tanks. It only costs around $25 to fill it at the local Airgas and that ought to fill my little tanks around 16 times.
