The attached photo shows the metal replacements I installed. The originals were wood composite that broke when hit by the heal of your foot. I believe these are the return vents for the heating and AC system. Our 8289ws is a very early 2014, manufactured in June 2013 and I believe Forest River corrected this problem by moving these vents on later models.
Regarding my Tire Traker. I have found that when the tires are cold, in the morning, this system registers about 47-48 psi. At this same time, three different digital gauges show 50psi.
On the road the pressure and temps, of course, vary based on ambient temperatures. I'm generally seeing the Tire Traker reflecting a psi of about 55-57. Temps, as I recall, are 80-105.
Bottom line for me is that it will hopefully give me a warning in time to pull over and prevent injury or damage.
