Do most state parks have a 30-foot length limit?

Not true. I'll bet whoever told you this is from CA or the East Coast -- both these areas tend to have state parks with a lot of small sites.

On average, about half the sites in all state parks are at least 40 feet.

See State Park Data for more info.
