Daveb1256, don't let them discourage you. When we first started out, we had a dolly because we could not tow our car 4-down. Yes, it can be cumbersome to deal with at times, but unless you change campsites every day, you are not dealing with it every day. Just at arrival and departure. We had a Master Tow dolly so I have no first hand knowledge of the ACME but I have seen a fairly large number of them in campgrounds so they must be popular.
I suggest you try to find a used one. When it comes time to replace your Elantra, find something that can be towed 4-down if you are still RVing.That is what we did and 4-down is much simpler that dollies.
