Just 3 balls... Easy to lift out of trunks since it has a handle on both ends. Rolls well, just don't try hairpin turns. In deep snow it might even skid pretty well, LOL.
I commonly will use this and a roomy 2 ball tote to travel with. If I need more than 5 rocks I just start taking basic 2 ball totes...
