Towing A 2018 Edge

On my 2016 Edge I got a battery disconnect solenoid from Roadmaster. When I plug the electrical umbilical from the coach into the Edge, the 12V feed (charge circuit) from the 7 pin connector energizes the solenoid and disconnects the battery. There was also a diode installed so that it can keep the Edge battery topped off. The Brake Buddy runs off of the Edge battery. Works really well.

Does anyone have a easy way to disconnect the negative battery cable on my 2018 FORD edge front wheel drive for towing?

Since you are so close to the GVWR, I wonder what the weight is on each axle. I would guess you are close to or over your RAWR. If your Edge has to be towed on a trailer or tow dolly (some are flat towable) you will be adding a fair amount of tongue weight to your rear axle.

Check owners manual under towing section for towing restrictions.

Yes. GCWR of your E450 is 22,000 pounds. Your 2014 should have the 7500# hitch although that was right at the cutoff when they upgraded from the 5,000# hitch. Either way, the motorhome can pull it.

Is your edge a V6 model? The turbo-4 is not flat-towable.

You'll want a supplemental brake system.
