Just to clarify: TV vehicle is a 2010 F150 FX4 crew cab, 5.4L, 6 sp tranny with cooler, 3.73 rear axle, tow pkg, trailer brake control, sway control, and 7350 lb GVWR pkg. Trailer is 28 ft with a dry weight of approx 5400 lbs. Fully loaded I figure we'll be around 6500 lbs.

You'll do fine! :)

This is a wise move on your part.

None of those aftermarket mods will provide any noticeable power or mileage improvements.

For the most part the folks who "claim" performance and mileage improvements have never ever really put the money where their claims are. They tend to "FEEL" an "improvement just because of a difference in what it SOUNDS LIKE.

I challenge these folks to do a before AND after dyno test. A dyno test will prove or disprove that they gained anything in performance.

Most if not all intake and exhaust mods IF they provide any improvement generally effect only the HIGHER RPM range which would be well above typical towing RPM.

I will say the BEST MOD is to simply lighten up on the gas peddle a bit. Folks tend to BURY their foot when climbing steep grades. With a 5.4 just let it do it's thing, YES you WILL SLOW DOWN some. YES you WILL downshift some, that IS the CORRECT way to go about it.

Even big rigs slow down on the steep grades and you can too, that is what the slow lanes are about. It is not the Indy500 and you don't need to act like you are in a race.

That 5.4 is a very happy engine even if you run 4000 RPM, it can do that all day.
