The 29V is roughly equivalent to the 29MV, which is what I have.
In my rig, the reason you couldn't mount a sliding door there is because the door when open would then cover the thermostat and wall switch (which are mounted on the wall between the master and the bath). Actually, the thermostat sits far enough off the wall, the door wouldn't cover it, it would physically block it.
I've seen pictures of these units that actually run a "pocket" door there, but I have no idea when that started or stopped.
