Do realize that if you are going to tow heavy, the new F150 is even lighter than before so it will be pushed around a lot by a big trailer. Also, it's still just a little 3.5L V6 so it doesn't have a whole lot of engine braking when going down hill.
Those 2 things above are what I consider safety issues. If you stick with a trailer small enough that those won't be an issue, you'll do good. However if you try to go heavy and think this is a Super Duty F250 truck, it's not. The 6.7L Diesel will have great engine braking for going down hill and the 7600 lbs weight of the truck will not let it get pushed around as much as a much lighter 5100 lbs 2015+ F150.
If you want a truck for double duty and as a commuter as I do, then just be reasonable on your trailer size.
Also the Max Payload and Max Tow only offer a bit heavier duty hitch receiver over the standard tow package. It won't handle average heavy tongue weights (13%) of 9500 lbs "loaded" campers. Again, you'll need to get a F250 Diesel to get a hitch receiver that will handle the heavier tongue weights of the heavy campers.
