btw, I installed 2 pairs of JT StrongArms on our Rockwood 8281WS this last weekend, 1 pair on the front landing legs front-to-rear, and one pair on the rear stabilizers rear-to-front. I didn't install the front lateral pair, since I already had Winfield cross-brace stabilizers (which mount from the top of each leg to the bottom of the other leg, crossing over).
Hopefully the post I linked above helped some with the install tho'. Would like to hear how you got on, and whether you're happy with the improvement.
With just the Winfield stabilizers the lateral movement was 95% gone, but we still had linear movement, and some center bounce.
Haven't camped yet since installing the linear JT's, but hoping they'll make a further improvement.
I'm also planning to install some scissor jacks on the front suspension sub-frame cross-beam, to further eliminate any center bounce.
Hopefully after all this the rig will be rock-solid
We'll see how it is on our next trip, around thanksgiving
