I have a little different take on it. If he's not planning on up-sizing later on, a 2500 would haul this trailer fine and it wouldn't be marginal at all. The only rating that would be even close is GVWR, but that number is meaningless because it's capped at 10k lbs for reasons other than the truck's capability.
Aside from the coils, a 2500 Ram is identical to a SRW 3500, so you're getting the same frame, axles, brakes, tires, etc. The RAWR on those trucks is 6500 and this trailer wouldn't get even close to that. The coils ride and handle a lot better than the leafs on the 3500s, so there is actually a tangible advantage to the 2500 on Ram trucks. Real world performance with this size trailer would be identical between a 2500 and SRW 3500.
If there's a possible up-sizing in the future, I'd agree that the 3500 may make more sense. OP said he was really happy with his current 2015 model, however.
