I, too, read RVParkReviews.com quite often when traveling. I weigh the reviews and also read between the lines. I have found most are pretty spot on.
I like to know if the park is really Big-Rig friendly as I don't want to scratch the coach with tree branches. I don't want to park in a mud hole, gravel is OK and I don't want the spaces to be too tight so we can enjoy our patio area.
I have marked several parks off the list just by the reviews. Once, instead of stopping outside of LA (all the parks had bad reviews), I just kept on going driving back to Palm Springs making it a longer drive than I wanted.
I find the reviews a valuable tool and have left reviews of campgrounds myself.
