Memphis, TN - T.O. Fuller State Park

We are planning a trip to the Memphis area in the early fall, and had considered staying at T.O. Fuller State Park for the several days we'll be there. However, after reading a few reviews of the park, we find that it's very close to a sewage treatment plant, and several campers have commented on a terrible foul smell in the campground. Are these complaints valid, or are the posters exaggerating? If any of you have first-hand experience with T.O.Fuller S.P., we'd really appreciate hearing about it. Thanks in advance for any information.
