I had rolling ones but got too heavy to lift in and out of the vehicle. I bought a garden cart at Costco and fill it up with my traveling machine and all the equipment. I roll it out the door. Unload into car. Drive to classes. Load back in cart and roll into class. This only works if you don't have stairs. I use this in Arizona but not in North Dakota. The extra equipment is also in totes so I am only lifting about 3 things in and out of the cart.
