Stuff like that is usually an indication of a ground problem unless someone has messed with the 12V wiring. Thoroughly clean the chassis ground and any other ground wires related to the lights.

Providing you have a wiring diagram, this should not be a biggie, like has been mentioned, grounding, but also you are simply gettring a feed back through the brake light switch would be my initial guess.  BUT who knows what creative mods have been experminted with on that coach ??
Could be simply a bad wiring issue in the brake light bulb wiring area, start looking at the wiring in the brake light bulb wiring behind the lens.  Sounds interesting / simple  ;D

Also by removing both brake light bulbs at rear of coach, see if the marker lights still  light up when use brake pedal ? Look at bulb sockets...

Agree, bad ground. Try a temporary wire up to the lights from ground to check. How about the turn signals?

Another possibility could be related to the trailer wiring plug, have seen some real interesting (creative) engineering in that area too that did not work.
