I hauled mine in a 5x8 single axle trailer that I have because it was easy to load and I had no problem. Renting a car trailer from u haul would be the way to go but if you have an easy way to load and unload, I would not be afraid to haul them in a pick up bed....
I restored all of them and will start retorting #20 this week. I just keep looking for them from other collectors, craigs list, swap meets and etc.....
