Have you ever weighed the trailer and TV. What is your tongue weight percentage? Is the trailer level? Low tongue weight and nose high can cause Porpoising.
Have you considered the placement of the axles on our trailers as the primary cause of chucking, porpoising? Our trailers are like teeter-totters in that they pivot about the axles, which causes the bouncing that we feel in the cab. Yes, we can control pin weight and load distribution but that doesn't offset the placement of the axles, which produce the teeter-tottering effect. I've found the cheapest "fix" is stiffer shocks and airbags to greatly dampen the bounce.
