Tow Vehicle Improvements
I'm a little concerned about pulling our travel trailer out west and being able to pull up steep grades. I have a 2010 F-150 5.4L and was considering making a couple of power improvements like a cold ...

I don't know why everyone is saying the OP should consider changing his gear ratio. The Ford F-150 he's driving has a 3.73:1 gear ratio which is great for hauling uphill. His gear ratio provides more low-speed wheel torque, which makes it easier to get the TV moving when pulling a trailer. That ratio also improves acceleration up to about 60mph. (Passing performance and speeds above 60mph is a matter of horsepower, NOT axle ratio.)
I don't think anyone was really saying that the OP should change gear ratios. They were simply telling the truth that it's the most efficient and reliable way to put more power to the pavement. If one really needed more towing power from their current gasoline powered rig, that's the first step. Intake and exhaust mods give minimal gains and then only at higher RPMs. They will affect towing about as much as shiny new wheels. And even though catback systems might sound nice, they can get old real fast when towing for hours on end. The tuner "may" give some gains, but requires premium fuel, and potentially opens a can of unknown worms. I think you're right. No need for changes.
