Never had an issue with that over the many places we've gone with the hitch. I would add though, that unlike springs which have a more consistent spring constant, the urethane "springs" resist compression more as they are compressed. So while they may compress easily at the beginning, they become more difficult to compress as the force is increased. I think this is what helps prevent the urethane from "bottoming out".
That is what is called a progressive spring rate. The bars have a more linear spring rate, and a linear spring rate is better in this situation.
I also tend to end up at rough places, dirt roads that get worse near the camping spot, so I have to take the bars off before I get there. The bars are easy as I just use a lever to unload the spring, but the Anderson requires jacking up the tongue?
