I own a 2003 Damon Intruder.
My owner`s manual states that you should NOT operate the slides until the motor home is level to avoid binding and other damage to the slides.
Also, I found out the hard way that the drivers side slide has a motor control board that is riveted upside down in the motor compartment.
There is no cover or protection of any kind around this P/C board. This is a "through compartment".
Storiing fishing poles from the other side, the metal ends of the pole shorted the P/C board.
As always, this will happen when the slide is extended.
