Here you go. 2018 F150 max tow 3.5 towing a 2017 Reflection 315RLTS. 38 ft long and 10995 max gross on the trailer. 1200 lbs tongue weight. Proper hitch with 1400lb bars. Towed no problem at all. Also could tow the same camper with my brothers 2017 F150 not max tow 5.0 with 3.73 gears. Also pulled it no problem. I also used to tow it with my 2009 f150 max tow 5.4. Honestly I hated the 3.5 Ecoboost. Sounds terrible. Got worse mileage than my brothers 5.0 and similar to my 5.4. Has power to pull no doubt. F250 with a 6.2 will drain your bank account when towing. Expect about 35l/100km. The 3.5 was about 25-25l/100km. Similar to my old 5.4. My f250 6.7 powerstroke is about 23l/100km and is around 12 l/100km when just driving. Doesn't matter what you have, when your are towing that much weight you know its back there.
