I tow a 3000# boat but rarely more than ~25 miles. The Bronco does fine at highway speeds. Power is a non-issue. Stability is fine.
My previous tow vehicle was a 2009 F150 with the 5.4 triton. The Bronco is more stable and has way more power.
I just did the first oil change (15k miles) this weekend after installing a UPR drain plug (10k miles) on my 2.7. It was SOOOOOO much easier being able to hook up a .5" hose to the plug to start the oil drain instead of the huge splash of hot oil the factory yellow plug does. Damn, it was so...
I use one of these:

It's slow but works.
We have a similiar trailer in my boys' Troop. The GVWR of our trailer is 7500lbs but I have no idea what the trailer weighs with our typical load out. Fortunately, we have somebody with an F150 to tow for now.
There's nothing to communicate. You'll find out from Ford when the status changes on your Bronco. The dealer doesn't know anymore than you do.
I bought my Bronco from Woody Anderson. I had no issues.
