We'll have my first travel trailer next month which we will hook up to the F-150
F-150 has 110k km, built 2006', 5.4l, tow package, 7200# GVWR package, 3.55 Limited Slip Axle, 275/65Rx18 tires
Trailer is a 17ft, 3.880 dry axle weight, GVWR 7.000. We are used to travel along "less is more, so the trailer will not be heavily loaded.
However, some folks told me getting a Gryphon with a decent tow tune is a must.
If so I would aim for less HP but more TQ and improved transmission shifting, makes a total difference when pulling any trailer.
Also I want to take into account lower fuel quality which I experienced now and then.

So I thought about maybe four tunes

87 octane - for towing (my expected default for towing)
87 octane - fuel economy
91 octane - for towing
91 octane - fuel economy

Does this make sense? What is your recommendation?
