Just because you can does not mean you should. You will be stopping two vehicles with the brakes of one on a dolly.Towing is hard on the guts of the trans. Just had the trans gone thru on the Explorer, first thing Martin told me was NO TOWING. Might cost a bit more for the fuel in the truck but what is your life worth?
That is not to say i have not towed with a dolly. Short distance, lower speeds, avoided traffic and as many hills as I could.
My diesel has 4 wheel discs that work very well. A while back I had to tow a tractor on a trailer with no brakes. Guessing the combined weight was about 4000 pounds. Made my truck an absolute pita to stop. Your life, your equipment do as you chose. Glad I do not live near you....
