Hi I have a 2019 f150 5.0 with the same symptoms. It struggles to crank after hauling the travel trailer. I dont know if the battery is low as it will start fine after it cools off. It may be bad battery but it's fairly new in terms of years and low miles. It should have at least 2 more good years. Any luck finding your issue?
I am having the same issue with my 2018 F-150. Its got the medium duty tow package so I had to add a Curt Blutooth brake controller but other than that can handle my 2021 Highland Ridge Olympia 26BHS just fine. We got to a KoA the other day and shut off the truck to start unhooking. Went to start it back to back up on the leveling blocks and it wouldn't start. It tried but wouldn't turn over. Called State Farm roadside and waited about 15 min for them to get there. When he got there I tried it one more time real quick before he attached his jump box and it started right up. I think it has to do with some sort of heat buildup that when it cools down it can start just fine. If I leave the truck running for 10ish min then turn it off it will start right back up but its also been cooling off at that same time.
