It depends on you and what you want vs what you are willing to live with. Most of my 20 years towing RV have been with duallys, so I am used to no drama towing.
Last year we purchased a F150 max tow and a new smaller trailer. Its about 8,000 loaded. We did a 5000 mile trip last summer. It did wonderful but I have upgrades throughout the truck.
I have always upgraded shocks on every truck to the Bilstein 5100 series. This truck I added 10 ply E tires and a ride control air bag system. I also use an old Hensley Arrow hitch. The only problem that I had was in high winds when the Hensley Arrow hitch and the factory f150 sway control began fighting each other. Once I disabled the F150 sway control we had zero problems. My wife is very comfortable towing this combo and she believes it is one of the best combo's we have had.
Good luck, research you capacities and limits, and if you go decide on the HD platform, skip 3/4 and go to full ton SRW. No real penalties for the payload increase. I love the F150, but know that once the kids are gone, a truck camper is in my future, and I will go back to HD's again.
