As for the tire monitors. I set them as per the vehicle recommendation at 65psi. cold. Of course they go up as soon as I head out as would be expected. I did find that when I was taking trips in the winter the cold pressure would need to be increase b/c the outside air was colder. Then I re-set it in the spring. I did e-mail Darryl Larrence right after I purchased them to check about how much variance was acceptable. He said that a few degrees difference between tires was normal. As long as I'm in a range of about 4 degrees up or down between tires, I'm usually satisfied. Hey I finished the couch to bed modification and took out the last of the dinette seat. Will try to get some pics this week.
