Depends on your skills and time of day. If cars are parked, definitely not. If early or late, there is sufficient property, but could be tight depending on your trailer and skill.
I'm not sure what size your travel trailer is, but I would be careful. I'd maybe only try it at the magnolia plantation, as the parking like is a large one way parking, and I'm sure you could turn around as you follow through the parking lot. (Check Google maps and I'm sure you can get an idea of what I'm talking about). Though, I wouldn't risk that anywhere else. I'd suggest using a car (if you have one) to travel to the oakland plantation as it's parking area is tiny. Hope that helped.
