youd be fine with a 2 horse aluminum gooseneck. You already looked up your trucks OEM reccommendations. That is a great first step that seems to be lost on so many people.
Just follow through and look up the OEM weights on the trailers you want. "A" gooseneck or "A" bumper pull doesnt mean any more than saying "A" truck.
Lots of 2 horse aluminum goosenecks will be fine for you. My two horse aluminum gooseneck sundowner weighs 3600 lbs empty. Add 1000lbs of gear, and 2000 lbs of horse and I am under your limit at 6600 lbs.With lighter horses and less junk you'd be fine. The exact same model trailer as mine but in a 3 horse is 5400 lbs. Big jump in weight as the axles, framing , wheels all have to be much heavier. You are not going to find a 3 horse gooseneck that will not over load you...
You might find a 3 horse bumper pull but its going to be close to 4000 lbs. Add three horses and no gear and you are at your limit.
Id look for a 2 horse aluminum gooseneck with a 4 foot tack room/ sleeping area. And let your friends worry about transporting their own horses.
