It does help, because HCC has several campus all over the Houston area. I used to live in Stafford about 12 years ago. There are no RV parks/campgrounds in Stafford. However, there are some not too far (by Houston standards) away.
Just up Highway 90 (also known as South Main) is Lakeview RV Park. It's big, well lit, very nice and secure. A lot of people use it for the Medical Center. Highway 90 cuts throught the middle of Stafford so it's a fairly straight shot. And since they redid the road a few years back to semi-freeway, there are not near as many lights. Probably about 10 miles - 15 minutes or so.
Closer is All Star RV Resort. Don't know anything about it except its tucked away behind PPL Motorhomes which is at the intersection of Beltway 8 and Highway 59. Might be a little more convoluted to get get to, but less miles as the crow flies.
There are a couple more out in the Richmond area which is past Sugarland. Riverbend RV Park and Shiloh RV Park. I think they both are fairly small and probably 15-20 miles away.
Then a little farther than that is Brazos Bend State Park. We've been there several times (never camped as its only about 10 minutes from our house) and its fun. Trees, fish, gators, and observatory - what more do you need?
