I think you are over thinking this a bit. Unless you have an issue, you should only need to adjust your air pressure a few times during the season. I set the pressures in the spring when the MH comes out of storage, then again in the summer when it starts to get really hot, then finally in the fall when it cools back down. If your tires, rims and valves are good, the cold tire pressure will not change. Just watch the TPMS to make sure.
Like Dutch said, get your MH weighed and use the inflation chart from the tire manufacturer to set the cold tire pressure. If you set it to the sticker pressure, that would probably be okay until you can get it weighed.
