Some if depends on what type of camping you do. If you are a weekender or occasional user, the movement you get might not bother you & a Tri pod might me enough. Being fulltimers we needed more than the Tri pod. While it helped to a degree, it didn't do what I wanted. Dutch even added an aftermarket additional set of arm jacks at the very rear of our coach. Again, it helped some. Once we added permanently installed stabilizers our movement was eliminated. Even in high winds we are nice and stable. I also love the fact that Dutch doesn't have anything to put up, take down or store. I wouldn't have any 5th wheel without them. Hugs, Di
