No need to come a knockin,

this trailer's not rockin. 

It has a ROK STOPPER!!

The ROKSTOPPER is a uniquely designed (patented) fifth wheel / travel trailer stabilizer. The  ROKSTOPPER  works similar to chocks and wedges in that it limits the rolling motion of the wheels.The ROKSTOPPER cost less than half as much as chocks and wedges, and  is light weight  (3lbs.) and compact (5 cu. in.) for easy storage.  The ROKSTOPPER is easy to use and effectively reduces the unwanted rocking motion associated with the parked camper.

The ROKSTOPPER is intended for use on steel wheels with wagon wheel spoke and bullet hole designs.  

The ROKSTOPPER comes as 2 units one for each side of the trailer.  I believe the ROKSTOPPER to be the best value in a trailer stabilizer on the market.  If you want to limit the rocking motion of your travel trailer try the ROKSTOPPER.
