When they say to do your air pressure cold nobody seems to know if that is 40 or 50 or 60 or what ever depending on where you live and the elevation!
Cold means you haven't driven it and has nothing to do with ambient which could be 0 or 110F. Elevation doesn't seem to have any real effect, except for the adiabatic lapse rate that creates a temp. drop with every 1000ft. of rise. All this is just one reason why I always recommend a cushion of 10-15 psi over what the inflation charts say and a good example might be for driving out of Death Valley and up into Yosemite NP, where you're most sure to find summer snow at Tioga Pass.
Still, there are those that insist on following the inflation charts to the letter, but think nothing of these changes in temp. or a 200lb person moving about inside the coach. I mean who wants to stop and add or subtract air, as conditions change?
