Q:

How do I express "I slept in a tent" in Japanese?

How do you say:

I slept in a tent on/at the campsite.

I've been trying to make sense with it for a while now and I just can't make it work.
I think I know the vocabulary needed: 寝ました, テント, キャンプサイト and maybe 一張? If you know words that would fit better, please tell me.

A:

I slept in a tent on/at the campsite.

You could say...

キャンプ[場]{じょう}で、テントで寝ました。
  (Lit. slept in a tent, at the campsite.) 
キャンプ場のテントで寝ました。 as suggested by @naruto.
  (lit. slept in a tent of/at the campsite.)   
キャンプに行って、テントで寝ました。
  (Lit. went camping and slept in a tent.)
