1999 F-150, 5.7 litre gas, so-called "trailering" package which was basically a hitch receiver and a trailer electrical socket but retained the stock frame and brakes.
I later graduated to a 6-litre diesel with a real trailering package (beefier frame, substantial hitch frame, bigger brakes, better cooling, stouter transmission with trailer mode, etc) which was a totally different truck and you wouldn't even know the trailer (loaded or empty) was back there.
That seems like plenty of truck for 3500lbs. I pulled vw drag cars all over the east coast with a 1993 Ford Ranger with a 3.0l 6 cylinder on a twin axle trailer without issue.
Obviously, a bigger truck with more power makes it more comfortable.
