F150 with a new Travel Trailer

I think the biggest concern would be the 1300lb CCC! That’ll be eaten up fast. It’s one thing to run a vehicle at it’s capacity, but it’s quite another with a trailer as everyone knows how well (not) they are built. You’ll be maxed out on every trip. And with the 5.4 of that vintage they weren’t the most powerful. But a good tune from 5 star tuning really wakes up the hidden potential in these motors. The drive by wire in factory tune doesn’t give you the full potential. A good time will give you real time throttle opening.
Knowing how it works I would say with a good tune it will be good, but a maxed out trailer will not.
