I promised a number of RV.net forum members that I would review our new Waynes stabilizer after our first use, so here it goes.
CAUTION: Yes, the stabilizer worked great, but be extremely careful where you place it under your RV. Read on to find out why!
We use a tripod stabilizer on our pin and a set of Rotochoks between our wheels. The rear stabilizers that came with our RV are the scissor type which do a reasonable job of stabilizing the up-and-down motion at the back of the RV, but do absolutely nothing for side-to-side motion. We have opposing slides at the rear of our 5er which accentuate any side-to-side movement, especially when someone plops down on the sofa.
We started looking for ways to minimize this side-to-side motion. We read a few reports on the Wayne's stabilizer and decided to give it a try. The stabilizer definitely took care of the movement, but we have a serious word of warning to all who are considering it. DO NOT try to put it under your end cap! We will discuss this further at the end of this page.
The stabilizer itself is pretty simple. Nothing but a tubular aluminum base that sits against the 5er with tubular aluminum legs that go down at an angle on each side and attach to aluminum feet. The feet have a hinge in the middle and an extra bolt across each foot that faces towards the center of the stabilizer. If you look closely at the picture below, you will see a blue nylon strap lying on the ground between the legs. Also on the ground, just under the left edge of my tag, you can see the brass colored ratchet that is used to tighten the strap. Just place the stabilizer under the 5er, attach the strap to both legs and tighten until it is firm and solid. This picture also show the scissor type rear stabilizers that came with our unit. They work great for up-and-down movement, but do nothing for side-to-side movement.
The principle of the Wayne's stabilizer is simple geometry, any horizontal movement in the direction of one of the diagonal legs would also be converted into an upward movement as the diagonal leg tries to straighten out. Since plopping down onto the sofa does not exert enough energy to lift our 13,000 lb. RV, the RV can't move sideways because there is not enough force to also lift it up.
The stabilizer comes in a nylon bag that is used for storage between uses. The size of the bag is something like the bags that small folding chairs would come in.
Bottom Line: The stabilizer definitely took the side-to-side motion out of our 5er. We are very pleased with its performance.
Caution on installation!
At first glance, the logical place to put the stabilizer is under the fiberglass end cap. We called our Everest support line when we first received our stabilizer and asked them if that would be OK. The technician recommended against it. He said that the end cap is securely fastened to the frame at each side of the 5er, but there is basically no real support in the middle of the end cap. This is probably true of just about any RV that you can buy. If you don't see a solid support, there probably isn't one.
Here is how we solved the problem.
Here are some pictures showing how we solved the problem.
|At the back of our RV, there are pieces of tubular steel about the
size of a 2 x 4 attached to the frame and the rear stabilizers are then
attached to the tubular steel.
We went to Home Depot and got a 2 x 12 and cut out a cross member that rests on top of the existing stabilizer bases between these pieces of tubular steel and extends full width over the frame just behind the tubular steel.
|This gives us the equivalent of a 2x4 resting on the frame behind the scissor jacks. By placing the stabilizer under this new cross member everything was very secure.|
