I can't remember how. Must have managed it as we haven't that much more stuff than last time.
We have
Large tent
4 x sleeping bags
4 x mattresses
picnic table
stove & gas
box of stuff - pans, bowl, plates etc
assorted balls
food
clothes
children
just looking at the car and estimating where things have to go there is no room at all for any clothes.
Should I look into roofboxes? or a trailer?
