RVParkReviews.
We have been part time rv'ing 17 years and been to 175 different RV parks to date; we even keep our own records!
I use RVParkReviews a lot. I count on them and this Forum. Lots of info both places.
When using RVParkReviews I do not go back more than 2 years at the most. I throw out the high and the low and read the middle ones. And, of course, see who posts them - lots of people on here I trust; but there are some I just toss.
Only been "nailed" about 2 - 3 times. Live and learn. It was dishonesty. I don't tolerate that well at all.
