x2 on the hubs. Manual vs automatic hubs come into play when towing a 4x4 Tracker four down.
What ever your manual says you need to have to tow with the dolly, if you have the wrong type it is 'real' easy to switch them out. So my RV dealership said when I dropped my Tracker off to get a base plate etc.
Turned out I had the manual hubs so I didn't have to switch them out.
I'd also make sure that it states in the manual that you can even tow it on a dolly before you do it. Many will show a picture of the car on a dolly with a big red line thru it!! :B
