I just installed the front stabilizers on my fifth wheel and all I can say is "WOW" what a difference. It is rock solid and I havent got the rear on yet.
Yes I installed the fronts on my 5er last year and so much better than a tripod. I just purchased a set for the rear scissor jacks last week. I will install them as soon as this stubborn winter breaks. I paid $56 delivered on amazon.
