I wish you wouldn't Glenn, some of us only want to learn and occasionally be helpful, if we have experience with a specific issue.
I know it can be frustrating to look for help, and get anything but. Keep in mind that the large majority of forum readers are just like you.
Most won't reply out if concern what someone else may say/do, but we cannot all learn without asking the questions.
I am glad you were able to get clear of the storm safely a found the significant leak and repair it.
I keep a couple different size air line termination push to connect plugs in my box in hopes if I run into an issue on the road, I can cap the line and get safely off the road.
I learned on this forum about the kids bubble solution being a great leak finder, and have likely since used at least a gallon.(I have run out again and need to buy more)
Without this forum and the brave folks willing to ask questions, I would still be looking for why the truck would air down during an overnight stop.
