The M&G 2.0 looks like they are finally trying to copy AF1.

I've moved my AF1 to 3 towed vehicles since purchase. Nothing to it. My opinion is that it's easier to mount the air cylinder inside the vehicle than it would be to find a place under the hood to mount it and then drill a hole for the cable that's inline with cylinder. Looking at my 2018 Explorer, that would be a challenge.

Both systems require a hole to enter the cab. It looks like you'd need 2 holes for M&G if you want to connect to the towed vehicle's lights. I'd also be curious if M&G has a way to seal the hole the active cable has to go through. With AF1 you have the option of where to put the hole and it can and should be totally sealed when done.

To each their own. The good news is you are installing some system.
