My garage floor slopes but it is fairly level from side to side. I have two blocks that I put under the legs on the infeed side (because of the way I have the Mark V oriented).
If I remove one of those leveling blocks, the Mark V sits with one leg (wheel) suspended in the air. I interpret this as an indication that once leveled it will not twist easily. Because of this, I believe you can roll a Mark V around on an uneven floor with no adverse effect.
Once you have it in a location where you want to use it, I would check for stability and somehow secure it if it rocks but I feel that is all you have to do.
I am prepared to say that the Mark V will definitely remain in alignment even though you are moving it around on an uneven floor BUT it must start its roller coaster ride with the tubes properly leveled and secured.
Adding the Carriage and Headstock into the equation just makes it that much more stable when the locks are all secured.
This is a beautiful machine and it endures the hardships that we put it through if we just treat it and use it with care. It was designed to do just what we are discussing.
