I purchased an xxl Tutto which the 15000 fits comfortably. The issue with travel is the weight of the machine. Pre Tutto -I could lift the machine into my car and to class after I stored it in the case I had a very difficult time lifting the Tutto ( it creates more bulk - width). And have actually taken the machine out of the case when going to class. My next idea is to creat a ramp that I can roll the Tutto up to get it to my SUV tailgate;)).

I hope this helps.
