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.
