Car camping

I know with car camping you get a 12x30 space but do we think they’ll be super strict with the length. We have a mini van which is quite long and then a 10x10 canopy and a 10x10ish tent. I’m worried it won’t all fit 😭 there’s also 3 of us so it might be hard to find a tent much small nor do we necessarily want to have to buy a new tent. Lmk
