The euro high altitude fix is expensive and hard to get. Nu camp's fix is cheaper but not an easy install. Both do the same thing: reduce the orifice in the propane line down to 2mm. I made a reducer from easily found parts on Amazon. $15 plus shipping. Get a 3/8 female flare to 1/4 male pipe fit and then a 1/4 female pipe to 3/8 male flare fitting. Insert a small washer in between the 1/4 inch parts and screw them together.
I used a small washer I already had. The center hole was too big so I super glued a small nut with a 5/64 (2mm) center to it. Note the nut is on the side that goes to the propane hose so if it falls off it won't go into the alde.
Follow all the safety rules--disconnect gas, etc as explained in the alde thread
Disconnect gas line from Alde. Attach reducer to alde. Attach hose to reducer. Turn on gas, check for leaks, turn on heater. Got heat? Your good to go

Another option for high altitude operation, which should also benefit the refrigerator would be to carry an LP pressure gauge and adjust the LP regulator for a lower pressure at high altitude. Installing an LP quick disconnect or something similar would facilitate easy connection to the gauge.
I had one of these but sold it on ebay when I sold my last RV, thinking that I was out of RVing for good. Silly me.

The washer (or your nut) doesn't keep the ¼" NPT connection from tightening up, and it'll tighten up enough so the washer isn't loose in there? Or will it need to be glued in?

edit: these fittings at McMaster aren't right...

McMaster Carr has pretty reasonable shipping, from my experience.

For the female flare/male NPT, the only thing that comes up for me is an Inverted Flare fitting, designed to go on the end of tubing.
Thanks!

The female side does flare, and the male side is flat.
The NPT thread depends on a tapered thread male and female to tighten and seal, and the flare fitting depends on a male cone shaped end to mate with a similar cone shaped female... What am I missing?

I think what you're looking for is a ⅜ female flare (non- "inverted") to ¼ male MNPT.
And a ¼ female FNPT to ⅜ male flare.
To complicate things, from what I can tell, there are two types of NPT threads, straight and tapered. Also there are two types of flare, 45° and 37°. I believe the 45° is more common, but I I think it depends on the industry it's intended for.
I hunted for a while, ordered the wrong parts, and then thought I might get the parts source from @Tabster, to save some digging... But @Tabster must be out in the mountains, testing his new high altitude mod!
I did find what I thought would be the most difficult part, the tiny washer, in my electronics hardware bag.
So please, keep us updated on what you find!

PLEASE, anyone venturing to do this mod themselves, only attempt it if you are confident in your ability and knowledge of working with gas lines. Use the right sealant, and properly test for leaks. If you don't know what I'm referring to, get a professional to do this job for you. Leaking propane under your bed is a recipe for disaster, and a potential for death. You are responsible for your own self!

I spent my lunch hour looking for the gas side fitting with no luck, wish I'd seen your post first. I think my Alde side fitting will work, but if not I've got the other one in my cart.

(But I thought the 400 came from the factory with the problem corrected?)
