When we moved to Colfax there were two barns on the place. Margie Van Winkle measured one and said, "Yes, 26' 1", it will fit. Randy, Margie and some friends from college helped put in barn doors. Here is the grand opening in 2012: http://graestone.org/wp-content/uploads/2012/01/GrandOpening.mov

When the coach is in the barn, against the stop for the left rear wheel, the door shuts with one inch to spare.

Sometimes my coach tries to walk out. One time it tried so hard it bent the drop pin and popped the doors open. It really walks!

I have started it and backed it up, sometimes two inches. My coach walks. I always put it in park.

I feel like I should shake my finger at its nose and say, "Stay!"

Hints:

I have disk brakes in back and an emergency brake on the back bogies

I have a slow leak in the air bags

Wheel chocks should fix that.

The rear rear stays in place because of the chock. As the bag deflates because of the slow leak, the bogies swing up and push the front end forward. If you air up the bags, it will pull the rear axles forward as the bogies swing down.

Right?

Could be...

I thought the rear braked rear wheel rotates in the forward direction as the bogie swings up, because of the leak. Even in park there is enough lash in the FD that it could move a bit. I tend to set the brake and then put it in park because I don't want it moving forward even an inch. And then it did, anyway!

I think I was making it worse by pumping the bags higher, so the leak would take more time until it was sitting on the ground. Pump it up. Set the brake on the back bogie and let 'er walk. Luckily I am a quick study and after only three months I have figured out to turn the air off at the bags. I really wish I could find the leak.

Of course when I was going to empty the black water tank because it is finally dry enough to not get stuck, I tried to let it down on the left. (My sewer cleanout is not at the most level portion of our place... But then, in Colfax, what is not going uphill is going downhill.) Funny how the J.R. Slaten valves don't do much when the valve at the bag is off. Maybe I am not that quick of a study.
