Ramp Lake Moultrie

What is the best ramp where I can leave my truck overnight? Planning a trip thru the locks for the long weekend. I have a 2WD F150 pulling a 24ft boat so need a decent ramp. I have never had an issue at a public ramp before but just wanted to make that point.

Black's Fish Camp OR Canal Landing for a boat that size. I would NOT leave my rig at any public ramp overnight at Lake Moultrie.
