Always a pain in the neck to hook/unhook car and dolly, but if your car won't tow 4-down, it's the only option. Saturn did a great business selling to RVers because their vehicles towed well 4-down. I had a 97 Saturn... before that a Geo Metro, for which we didn't even need supplemental breaking with the big pusher. Recommendation from a friend who uses dolly... take the car off the dolly before driving to the campsite and let SWMBO drive it in; makes it a lot easier 'cause there's often limited space at the site to maneuver and park.
