110K is not high mileage for a newer Ford V8. If you haven’t changed the plugs, consider that change and a tune. It helps with shifting even with a minimal HP increase. Also, make sure you use Tow/haul which helps with shifting at the right time.
Years ago, I towed a 6000 lb dry weight trailer with a 97 Expediation. I think it has “enough” power, but it’s not going to be awesome. It was a handful in the wind and your Aviator is even smaller.
