Ignore that Max Trailer weight--it means very little when it comes to a TT. Your truck could easily pull a boat that size, but that trailer you're looking at, with it's heavier tongue, would be a load. IMHO, based on experience, you will not be a happy camper with that rig. Loaded with the family and dogs, with big trucks passing you on the freeway, and throw in a crosswind just for fun, and a curve or two and maybe wet pavement... I have towed overloaded, and it sucks.
Most half ton crew cab trucks are limited in what they can pull, because of their low cargo capacity.
