If you mean the Camping and Caravan Club site in Moffat then yes we were there two maybe three years ago.
Situated on the edge of the town, only a few minutes walking distance into town, also next to a garden centre with fishing facilities on the other side of the site with a shortcut to the centre through a gate. Garden centre has a restaurant, nothing fancy, but good quality basic meals at reasonable prices.
Moffat is quite a nice little town, don't remember many, if any, large shops but lots a smaller shops with a bit of character.
If my memory serves me right there is a co-op supermarket close to the site, only a couple of minute walk. Also a Mill shop with loads of touristy stuff, When we were there quite a lot of tourist buses full of Japanese seemed to stop on an almost daily basis.
The entry to the site can be a little tight for larger outfits, it's also hidden a little, you need to watch out for it. Only about 5 minutes drive from the M74, just in the town you take a right turn, almost a U turn heading back out of town, the road swings round to the left and you take a right turn then another couple of turns in quick succession before going over a hump back bridge into the site.
Quite a large open site, some hardstandings which are ( were) more compacted gravel, large toilet block which was clean but a little dated. Open to non members.
I would go back.
