Well I finally got around to diagnosing my slow leak on the rear passengers side outside dual. I have battled this thing for 2 years. So, I decided to take the SS liner off and check it out. Well as I pulled the liner off it caught the very edge of the 45 degree extension and I found the leak... It was a cracked valve stem. The stem was cracked right where the last few threads where the extension screwed on, on the back side of the valve stem. I just barely touched it and broke off.
So, now I am sitting in my RV barn with a flat and no real easy way to remove the lug nuts, remove the tire and replace the valve stem. So, I called Coach Net. I spoke to areal nice lady that took all the necessary info and said she would call back when she had the service call set up. That took all of about 5 minutes. The repair guy called a bit later and said they would be out in about 1 hour. Now I live 9 miles out in the country from the nearest town and close to 40 miles from where the service was dispatched from. I had to go to the post office so I met the service provider in town and lead him back to my place. Had it fixed in about 20 mins. My cost $39.20 for the "flat repair" and valve stem.
