The yawning is slow, as long as the sound stays consistent you are prob good. We heat the HW all night before launch on 120 then shut it down. Hot enuf to wash dishes and hands for a full day on the road. We travel with full water. The frig goes online with 120 three days out while we stock, then lp on the road until landing...
Do you have the whole house filter? We did but we pulled it. Using the blue camco stick works fine sitting on the rear bumper and can go into the freezer btw flights to dwell growth of nasties...

If your board take a pencil and run the tip across your keys then operate the locks. This transfers graphite to the pins to lub and prevent sticking. Never use wd40 or oil as it attracts dust and defeats the lube objective.... works on all locks...
Get a proper set of tire gauges. Consider something like a 160 for the rear and a 100 for the fronts. Gauge accuracy is best at mid scale. Good guages (rated, but not lab quality) around $25 each.
