With both furnace and stove, I'm suspecting you may have a regulator issue - regulator is producing marginal pressure/flow at altitude. The stove and heater use considerably more gas than the fridge. The other possibility is some kind of restriction in specific propane lines.
Our house is at 7600ft. My propane soldering kit is useless - the weak flame blows out easily, and it produces almost no heat. I had to switch to the yellow cannisters with a special soldering unit to doing any soldering on copper pipe. But that works like a champ.
Propane stoves do produce less output, and some don't like to work at all at high altitude, just like my soldering kit.
I understand the propane mix is slightly different at high altitudes. You might refill one of the tanks while up in the mountains and see if that makes a difference.
On my A122 A-frame, I sometimes struggle to get the fridge to light, although all the other gas appliances work correctly. Haven't been able to figure out why. But so far my camping has been at lower altitudes than my house. This weekend, we head to Ridgway, CO (I'm assuming you are in Colorado or Utah yourself).
