As many of you know we have season lease site this year. We had noticed varying degrees of trailer movement - someone walking through the trailer and feeling the movement - on our travels but now that we're spending more time in our ST29RL the rock & roll has become somewhat annoying. Wasn't front to back but rather side to side. So what to do?
Checked with our RV repair facility. There response was nothing you can do. Checked with the dealer we purchased through. Again, basic answer is just live with it. Read rv.net forums and got solutions from cheap & simple to exotic and impracticable. However, one solution that seemed to make sense was using cross braces to help stabilize the trailer.
After looking around for something affordable i stumbled on these at Harbor Freight
Used two of these at each end to brace the jacks. First day so a little early to report success but at first blush they seemed to have eliminated the side to side shimmy and shake. Still have a little movement from the suspension but that's to be expected and seems minor at this point.
Now I don't know if I would take these with while traveling. There is good accessibility to the rear jacks and they would be relatively easy to do while traveling. Bracing the rear only helped but there was still plenty of movement. The front jacks involve crawling beneath the trailer and would be a total pain to remove if the weather were bad. However they are easy enough to stow in the back of the truck or in the storage bin under the trailer. A breeze to tighten and to relieve tension. Cost about $13 each.
