What did towing the Edge do to your MPG? I know you have a diesel and i have the E-450.
I previously had a Chateau Class C built on a Ford E-450. Towing with my 2014 Ford Explorer Sport would knock down my mileage at least 1.5 mpg. That Explorer was what I just traded in for my Edge. Now on my Seneca (diesel) towing the Explorer maybe
drops the economy 1 mpg compared to driving without it. We haven't taken any longer trips with the new Edge but it likely will be about the same as the Explorer.
Just a couple more points about the Edge ST. With its electrically-applied/released parking brake, Ford has programmed the system to apply the parking brake whenever it feels it might be necessary. That is the reason the parking brake must be released as one of the last steps before towing and then the battery must be disconnected to keep it off. When the battery is turned back on the parking brake then applies itself.
I installed the Roadmaster battery disconnect system on my Edge to make it super easy to disconnect the battery. But instead of mounting the activation switch inside like the instructions indicate, I mounted a weatherproof switch behind the front grille. That way I can prepare the car for towing, close the driver door, lock the car with the fob, then walk to the front and push the disconnect switch. Then when at destination the first thing I do is hit the switch to turn the battery on so I can use the fob to unlock the door to continue the disconnect process.
I have attached a document I put together from the sections of the Owner's Manual. I found it easier to go through it like this instead of flipping pages. At least until it becomes second nature!
