Long story short, does anyone have any experience with or know if disconnected house battery cables (had not yet installed the house battery from winter storage) could in any way shape or form completely short out or eliminate ALL coach electrical power?

Long story,...was driving our RV from storage to residence and within 1 mile from storage facility lost ALL electrical power to the coach. Died right in the middle of the road with no shoulder to drift onto. Waited for a tow that never showed and, in the meantime decided to do a little investigating. Finding nothing obvious, I elected to check the not connected house battery cables. Really don't recall if the unattached ends were touching anything metal (like the empty batter tray, etc.), but moved them enough anyway to make sure they weren't touching any metal. Got back in the cab and waited some more for the tow truck (still did not show after 2 hours). I then decided I had nothing to lose by trying to start it again. Low and behold, everything seemed back to normal. Nonetheless, I got out the trusty duct tape and wrapped the ends of the not connected house battery cables just to make sure the ends did not come into any contact with metal. Drive the RV back to the storage facility and have arranged to have it towed to a Ford truck center tomorrow morning.

Is there ANY possibility the not connected battery cables were the culprit?
 
The Ford/cab battery charges the camper battery when Ford is "driving".

If camper battery connections are dangling around unconnected while driving, then they can ground out and since connected to Ford battery- have major consequences on the drive vehicle.

Yes- I believe the cab power system grounded out via the dangling camper battery 12V+ connection.
