I had the Tripod for years on our previous 5th Wheel, it worked ok.
Current 5er has MorRyde rubber pin box so I went with the stabilizer's mounted to the landing gear, the difference between the Tripod and the stabilizer's is night and day.
5th Wheel is much more solid with the stabilizer's.
Stabilizer's much easier during setup, do not have to store them inside, got mine for the front only (did not need them for the rear) from http://www.plugitright.com/RVStabilizer.html , good price, good product.
