Having trailer brakes better, but the real problem with dollies is the CG ... center of gravity. Most of 'em don't allow for enough tongue weight because if they did, the car would be so far forward the ramps would impact the bottom of most cars and almost certainly a "low rider." If the pull is smooth and there are no "displacements" from stable, they're marginally acceptable. But who hasn't had to change direction? Who has been on a contemporary highway without unavoidable potholes/sinkholes ... ruts. And in Louisiana ... bi-level-shifted roadways which are more like stairs than thoroughfares.
bummer ... I might find a better campground. an 18' lowboy behind a motor home? I wouldn't think that'd be much different than a crew cab/5er with a visitor. Must not be a state/federal RV site?@Shaark, there's no room for the trailer at the camp ground. I agree about the dynamics of weight bias. I've had to learn it through experience and had a few hairy situations.
