Ashuelot River Campground in Swanzey, NH?

Have any of you recently stayed at this campground in Swanzey, NH? Can't find but one review which was posted in 2009.

Are roads in to and in the campground navigable with a 38 foot 5th wheel? Are sites large enough for 38 foot 5th wheel?

Anything else I should know before going there.

We want to be close to Keen and Troy to visit with some of our relatives.

Thanks for your input and suggestions.
