Hi,
I had a deck that swivels, and would not leave the steering unlocked. Never had a problem.
I drilled 3/8" holes into the front, near the bumper of my minivan (or found some factory holes, I don't remember) and installed 3/8" eye bolts. Then I could use quick connect on the end of chains on the tow dolly to help secure the van to the tow dolly, in the event that one of the safety straps came loose.
I would tow about 500' or so, then double check the safety straps. Usually they would 'settle in' and need to be tightened a little bit. I did this because one trip I drove about 30 miles, then checked it at a rest area, they where loose. . .
Once - on the first week towing with it, I left out the tilt safety hold pin, and the ramp could tilt back each time I started moving. I fixed that by listing the 7 steps to hook up the van, and have it ready for towing. Then mentally counted the 7 steps as I went along.
I also installed diodes in my van rear tail lights. I put in a wire connector, and tee in the tow dolly lights. So as I hitched up, I connected the van taillights with the tow dolly ones, and the van running lights and brake lights came on with the motorhome and tow dolly ones. Not sure if required or not, but safer than not having them. . . It takes about 15' of wire, and I put a diode under each tail light lens, with two inputs and one output to the light. Inputs from the van and motorhome.
The diode packs came from Roadmaster, and are the same kind that I installed in my Honda CRV, and later I transferred them to my Ford Edge. I bought them at Camping World.
My biggest reason for buying the Edge is that I can tow it four wheels down, and not bother with the dolly anymore! It was a bit of a pain finding a location to store it while in a campground, and being alone, I had to pull the RV into the campground roadway, then hitch up the dolly, then move the car around to hook it up too. All the while blocking traffic. It might have been easier to just hook up the dolly and pull around to a parking area near the front of the campground, if I did not need to walk back for the car.
Have fun camping and sightseeing!
Fred.
