Before you blow these off because they are only rated at 2000lbs and Andersen are rated at 6000lbs you have to remember these go under the tongue jack and what is the weight of your tongue load less than 2000lbs then they will work! And if your trailer is a 5th wheel what is the hitch weight since you use two divide the hitch weight by 2 (you put one under each leg so the weight is not only on one block) and if that is less than 2000lbs it will work' You have to remember that the stabilizer jacks are not really jacks you are not trying to use them to jack the trailer off the ground all you are doing is trying to keep the trailer from rocking and rolling when you move around inside so your not putting the weight of the trailer on the blocks!
