Dp dss and I love to camp but tend to try to find campsites that aren't too expensive as we don't need a hook up or mod cons. We've been known to camp without loos even but tbh we do prefer a loo at least.
Ones we've tried and liked/loved are, Crimdon dene farm (C&C club certified) Strathmore Arms pub Teesdale, The Countryman Bolam (C&C certified) York House caravan park near Robin Hood's bay (takes tents), Barnard Castle (C&C).
The latter two have more facilities but the first ones are very cheap, around £5 per unit per night.
We're off to a new one midweek if it's not too bad weather wise and I'll post that one if it's ok. Sounds good by reviews. Also going to Keswick C&C again in August. Love it there. Although not classed as the same area as my title 
If anyone can recommend others they've tried I'd appreciate it. TIA
