Just brought home our new Road Warrior last week and it has the 6-point Level-Up system. It seems pretty solid sitting on the gravel pad with no stabilizing system attached. Contemplating whether or not I should buy a kingpin stabilizer or not (this is our first Fifth Wheel). My gut says to wait and see how it feels during our first outing in a couple of weeks.
A year and many camping trips later, I can unequivocally say that, if you have the 6-point Level-Up system (or equivalent) you should not need a tripod. Using Level-Up and chocking the wheels tight, it is rock solid. I can't see carrying a tripod and taking up precious cargo space for what
might be a nominal improvement.
