I'll have to try mine again, but I know a couple of times I tried to start the engine while slides were extended and it would not start. When it wouldn't start it was always a forehead slapping moment.
That is one of the reason why I never use the rapid camp. (Some of you might remember that work of wonder) Engine running and brake set for leveling jack operation and then have to run inside to shut engine off to extend or retract slides or awning.
Maybe things have changed in the last 4 years. Did they also kill the interlock for the awning?
