There have been discussions on how to reduce the wobble in a PUP. I am going to install 2 sets of BAL Lock Arm Stabilizing Bars on my Niagara. My first thought was to install a set on opposing corners, with each stabilizer having an arm pointing fore/aft, and one pointing left/right. After thinking about it a little more, I though it might be better to install the four arms on each of the four stabilizers- the front right stabilizer having the arm point across the trailer (side to side), the left front arm pointing back to the rear, the left rear arm pointing sided to side, and the right rear arm pointing forward. Both methods would have 2 arms addressing side to side movement, and two arms addressing front to back movement, but in a slightly different way. The instructions don't really address it, and show pictures of a 5th wheel installation with four arms on the front stabilizers. I am wondering if there is an advantage to one way or the other?
Really, any movement at all is seems to be transferred. Not so much sleeping, but walking about, entering/exiting, etc. I've got a BAL chock and the BAL Leveler, I keep my tongue jack short (Lynx + 4x4), and the stabilizers short (Lynx), but the wobble remains. The stabilizers are going to get installed, I only want to do it once. FWIW, I emailed BAL, the email was returned as un-deliverable because I wasn't on their "list".
The biggest improvement for wobble on ours was to step up a load range tire and put it right at 65psi. But that beat the hell out of the trailer while towing. Not sure what I'll do with this new to us Niagara for tires as I don't want to rattle it to death in transit.
When i had my pup i didnt have wobble when walking, when sleeping i could feel if the people on the other side moved a lot. Or if i did. I didn't ise bal chcks or levelers. I put wood under one tire, used 4 chocks , 2 per wheel. And had a stand for the front wheel so it didnt move. I used wood under the stabs, snugged them down then then tightened them another turn. Also made sure tires had full pressure. Not sure about your pup. It did move when i steped quickly on the stepper door. But im also about 225 lbs.
I installed two sets of the Lock-Arm Stabilizing Bar Total time from tool gathering to clean up was about 1.5 hours. The first one took about 35 minutes, the next one about 20, and the last two about 10 each. I mounted one bar on each corner, the front right stabilizer having the arm point across the trailer (side to side), the left front arm pointing back to the rear, the left rear arm pointing sided to side, and the right rear arm pointing forward. These arms have taken 80-90% of the wobble out of the trailer, I am really happy with how this product works. The wobble comes from the "slop" in the stabilizers themselves. These are the OEM crank down stabilizers, and there is a considerable amount of play in the stabs, at any distance. The lone drawback is that I will need to carry a dedicated 3/4 wrench to tighten/loosen the lock arms, the toolkit I carry does not have a combo wrench that large. I'll store it with the crank for the stabs.
