This may not be relevant to your problem...however...we HAD a 2008 Dutchmen 26bb (double opposing slides) ... we always remove our keys from ignition when parked ... ONE time, we attempted to start motor with slides out and nothing happened ... we quickly discovered it was a fail-safe to prevent you from moving home with slides extended (nothing in manual regarding same)
As I said...this may not be relevant to your problem, but good to know.
