When I moved (south to north) cross-country three years ago, I unintentionally moved my MT snails:
I placed my driftwood and gravel in a big rubbermaid container (covered) in the back of my topper-covered pickup. Parked in a hotel parking lot for about a week (house sold sooner than we could move) then drove north (in August). Stayed at my mothers for another 5 days (i think I remember flushing the container with water while there), moved to new house and waited for aquarium to arrive. Put gravel/driftwood into tank, filled with water, and found live snails!
So any of the methods mentioned above should be fine
