Andy, thank you for all the good information, those of us who have never built or participated in a modular group don’t know.
Thinking of storage at home, once I get the Styrofoam that I have stashed under my home layout a module could fit there. I could flip down the back seat of my car to transport a module. I can see that building modules, at least the frame and track would also guarantee they are all the same so they will match up when put together.
