I also have a 2022 25RDS. I fell for the "1/2 ton" BS too. I had a 2013 F 150 with the 8 cylinder engine and tow package. It also had Bilstein Shocks and Firestone air bags. It pulled the trailer fine. Towing it was another thing. I towed it home from the dealer and it scared me in the high winds and truck traffic on I-35 that day. Three days later I had it loaded, set up with a Blue OX 1300lb WDH and took off on my first trip. Again, pretty windy and "truckie" on I-44 and I-40. It was an interesting trip driving with the trailer brakes and accelerator. I made it to the Campground spent a week and drove home. Scary at 55-60-mph. Trailer went into shop for warranty issues and on the way home I bought a 2020 F250 6.7ltr Powerstroke. A month later when I FINALLY got my trailer, I set up the Blue OX and took it on the road for another trip. Smooth as glass with no sway, no wind whip, no struggling on the hills and no squat on the truck, and no puckering on the downhills with the engine braking.
I have put 15k miles towing in CO, WY, SoDak and the UP with 0 towing problems. I must say though, that anyone that would pull this fully loaded trailer with even a F 250 Diesel at 70+ MPH should have their head examined. Too many jackasses on the road that will pull out in front of you, cut you off and even brake check you. My towing speed is 62mph for maximum safety and fuel economy. Enjoy your 25 RDS but be very careful with something as light as an Expedition towing it. Not enough oomph in the ass end, and a strain on that engine. Good Luck
