Travel trailers do not experience "chucking" because the hitch point is almost level with the rear axle so it has no leverage on the front to rear back and forth movement that is "chucking". The 5th wheel hitch is located some distance above the rear axle so there is a lever moment that allows the chucking to take place.
What a TT DOES have, however, is "porpoising" which it the up and down movement of the coupler/hitch connection resulting in a movement similar to a porpoise as it comes up to breath and then returns to the depths.
This can be quite uncomfortable just as "chucking" can. Just like a 5th wheel, not all TT do it and it often depends on the road surface. It can usually be controlled however by a combination of speed adjustment and hitch adjustment and loading providing your shocks are up to snuff.
Swaying, the horizontal movement back and forth of the trailer, is usually not a concern if the hitch is set up properly, the trailer is loaded properly, and the driver is paying attention to what he/she is doing. There are many sway prevention/reducing hitches on the market also that help.
