Mike, You find a few other CG Review sites on the
RV Related links page.
I should warn you that these reviews are NOT necessarily factual. If it's just one or 2 reviews I'd be leary. I have read many a good or bad review of CG's I have stayed in and often found the review to be an absolute exaggeration or flat out lie. You have no idea who posted that review. A good review could have been from a friend of the CG or possibly the CG owner himself. A bad review could be the CGs competition. Even multiple reviews can be questionable. AND what you may consider bad others don't and vice versa.
I have found the best CG reviews can be found right here on the MOC forum. Got a CG you are interested in? Just ask about it and you will find a member or 2 or more have already stayed there.
