I would recommend a close look at the 38 psi tire. You may have a nail or bad valve stem.
Mix up a strong solution of dish soap. That is 2 parts water
1 part dish soap. Completely cover valve stem then wiggle it.
Nails and screws can be difficult to see. If it were mine I would take the tire to a tire shop have them air it up to about 125 % of sidewall pressure and put it in the water tank.
A TPMS system is tailored for this situation. If it is a nail it may hold air when stationary but loose air when under way. So airing up and checking pressure tomorrow may not show up a nail in a tire.
Last month I had a nail in my Subaru. The TPMS warned me before it was a problem.
Then two weeks later the TPMS alarmed that a tire was low on my truck. A 80 psi tire was down to 65 psi. I decided to drive 15 miles to a tire store without the 5th wheel. I had gone less than 1 mile and pressure dropped to 60. Another mile it was 55.
I decided I would not make it and put on the spare and went back to the trailer campground. Home was only 25 miles away from campground.
The next morning took the tire to the tire shop for repair. The TPMS showed the tire still had 50 psi. Bad valve stem and only lost air while tire was spinning.
