I am assuming you're going with a tandem axle trailer. Depending on trailer axle placement, trailer length and weight, load weight, etc., you will need to have the bed weight calculated. I've pulled various gooseneck horse trailers (with my dually) and they will surprise you every time with how they are balanced and how much weight sits in the bed. With the right trailer, you might be able to get away with it but like others have mentioned, the truck may be a little light to be leading the charge even with great trailer brakes.
