Ram does too. My 2500 has a class V, they’re even nice enough to give you a reducer if you don’t wanna buy a new hitch! Lol how could you pass up a deal like that?!?
Honestly I think y’all are worrying for nothing. I don’t know where these ratings come from, it’s just odd to me. My parents towed a 30’ bumper pull steel horse trailer all over the country with me and my sister to rodeos with a 1.5” shank, 2” 5000# ball ON THE BUMPER of a 1980 GMC 1 ton. Those old trucks don’t have near the capability of all this new technology. If that welded chunk of 2” square tube with 4-6 bolts directly into the frame can’t handle a 7000# boat on wheels, I’d be more than surprised.
I’m not saying it’s right or wrong, but from an engineering stand point, it doesn’t add up that the hitches can’t handle it.
