Since these are RV forums, what remote means to us is where we can still get to with our RV. Our days living out of backpacks in the High Sierras over 10K feet are in the past ... although I could probably still do it if I had a reason too using the gear stored in the basement. In Colorado we have had our RV over 11K feet and it still runs fine up there, but we don't RV camp at those altitudes due to density of air reasons. Do propane RV appliances still work above 10K feet?
We don't care about designated places to camp, only legal places to camp - where we can still get level with not too much tire hole shovel work or tire blocks not higher than around 7 inches - and where the hermit/etc. types don't come out to meet us with shotguns or worse. I like the long views one gets out in the deserts as opposed to being closed in by trees. The DW likes wherever the rocks are, with preferrably minimum rattlesnakes among those rocks.
The information on Jarbidge does indicate a hundred or so folks full-time living there, along with a place too to stay and eat if a visitor or two needs it. They also appear to have a few limited "Jarbidge social" events. The residents must be able to maintain and repair their vehicles way out there, too.
We don't mind long gravel road RV runs. We take it slow and easy so as to keep the rig together, but the roads must be wide enough or have hard pack pull offs for faster moving vehicles to get around us.
