Shamrock 21SS Ricking problem.

I own a 2013 Shamrock 21SS. Love the unit but have a huge issue-it rocks like a boat on the ocean!! Unit is leveled, legs are down on level blocks and it still rocks! Was told to purchase stabilizers at the extra cost of $400! For what I paid for this unit I shouldn't have to put out extra $$ for no rocking. It looks like a design flaw in the way the stabilizer legs are attached to the chassis. They are only attached on C channel and when the legs are down this flexes causing the unit to rock. Any ideas on how to stop the rocking?

I watched a guy on youtube rig up slide out stabilizers. He said his rv rocked even with his four stabilizer down, but with the slide stabilized, no rocking. Ours has a little movement, not too bad, but even so, I bought these today at camping world.

You'll likely find in your owners manual that it recommends specifically agains these slideout supports.

The more solid you make your frame so the trailer doesn't bounce on your tires/axles, the more solid your trailer will be.

Try a Valterra Stabilizer and also try something under your steps. Or, simple scissor jacks at the axles will also help. The x-chocks help the front to back motion, but you need something to shore up the total frame.

Just remember, the OEM "stabilizing" jacks mounted on your trailer only stabilize to a point. Many of us have taken other steps to firm up our trailers even more.

Strong Arm type stabilizers will help. Either buy or build your own.

if you use them and they cause problems, you'll void the warranty.

Actually, after I read your post, I checked my manual and all of the other materials we got with our trailer and the subject of supporting a slide isn't mentioned.
