I asked specifics about his ride, as one man's "bone jarring" could be another man's "acceptable". And then gave general information about what affects ride.
One good example is improperly sized spring bars (not his case, it appears). If spring bars are too heavy, then they flex very little during suspension movement. This will cause the TV to ride rougher. Spring bars too light will cause lots of flex in them. They flex to a point, tighten up, and start transferring to the TV. Sometimes this can cause a porpoise like action.
My guess is the OP is riding on the overloads or even engaging bump stops but it's hard to know without some specifics. The 250s are sprung a bit light in the back, and that's a heck of a lot of tongue weight. And that's assuming he's actually verified the weights.
And trailer suspension can soften some harshness felt in the TV. But won't necessarily keep it from "bone jarring". My old trailer had 5300# axles, new trailer has 4300# axles. Same TV. New trailer weighs more (don't get me started on the lightweight axles). There is a pronounced difference in how the two pull. New one wallows along, the old one you could feel every little undulation in the road.
Anyhow, that's my thoughts, your mileage may vary.
