I have found a nice picnic/swimming/sight-seeing place and parked my motorhome on its car park. Am I allowed to spend the night there?
Basically yes, but there are two exceptions: If the car park is within the protected area of a National Park then you may not spend the night there. Such car parks do exist, an example is the “Tiveden” National Park. And sometimes you find local signposts that say otherwise. Their legal status is however in some cases questionable, so the decision is up to you whether you “take the risk” or not.
