Thank you for your for your advice. Checked all tires cold late morning here and found one at 59 psi. Corrected that, looked for a decent gague in Walmart, no luck. As we head South there will be more opportunity to get a digital gague.
A mistake that I have been making is airing up late at night. In the future, I'll air up during the day on tires that haven't been driven. Sticking with 50 psi, de junked the trailer and truck bed today. Wife and I feel that we are under payload limits. We have been in rural Maine for a month and appreciate the convience and economy of our Jayco Whitehawk.
