We too get the "porpoising" when going over bridge joints or a really rough road elevation change. Have over 2,500 lb pin weight. Have tried several things including changing rear shock absorbers. Nothing seems to make much difference. Pulling a near 14,000 lb 5th wheel when fully loaded. Have learned to live with it and have traveled the same roads enough now so know where to slow down to reduce the drama. First few times thought the rear wheels had lifted off the road. .
