I use a Magna folding handcart and hold things on it with a bungie cord. I do have to take things on and off to load/unload at the car but it is easier for me to lift things in and out of the car that way. I use the cart for a lot of different things (moved bags of mulch etc) and it was less expensive than a sewing machine rolling cart and has many uses. It also folds flat for storage which is a plus. It holds up to 150#. I got mine on Amazon for around $25 but I'm sure they are available other places as well. I love mine
