I use one that folds flat which I bought from Pets at home. It's really easy to fold & pop-up. I've used it on the beach, camping and in the car.
The dogs can see what's going on and also are shaded in the sun. If I can find the brand name I'll post it on forum. I would definitely recommend. I also have two ground stakes with long chains so my pooches can mooch around safely if I'm at the stove etc. and they don't need to be crated, it looks a bit ugly to have the dogs on chains but it gives them freedom to be outside when I can't keep a close eye, they have been very useful too. (I have two adorable, well socialised chihuahuas).
I got a folding crate from ebay, good price and size but it does not fold as small as I hoped, hopefully will fit in the car!
