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.
We also have the BAL Lock Arms and dumped the tripod. They work better and are much easier to set up than the tripod. Shopped around several brands before buying, and found the BALs to be well made (BAL is a major OEM supplier to the RV industry) and are about half the price of others.
