• The heavy side of the trailer, compresses the leaf spring and in the process reduces the arc of the spring.  The flatter spring extends and pushes the shackle toward the equalizer.  This movement forces the axles closer together.

​The axles of most RV trailers are out of parallel, sending vibration damage through your RV.

  1. An RV trailer only ¼ of an inch out of alignment, over the course of 5,000 miles, will scrub the tires an equivalent of 125 miles sideways!  
  2. Excessive tire wear is just the early warning sign of more problems to come.
  3. A miss-aligned RV is like a rolling earth quake.  
  4. Vibration through out the unit is prematurely aging the entire RV.  
  5. The appliances, electronic, gas / water lines as well as every fastener holding the cabinets in place and the entire unit together are all the victim of vibration damage.

The primary cause of RV miss-alignment is lateral unbalanced weight.

Excessive tire wear is an early warning sign of more problems to come.

We choose our RVs primarily on the basis of an interior floor plan that is pleasing.  Wives usually rule.  Designing a home on and within a mobile platform is a space and weight conflicting exercise.  It is no surprise that weight totals, curb side versus street side vary considerably.  This side-to-side weight differential causes most miss-alignment issues. 

  • The lighter weight side of the trailer, allows the leaf spring to arc more than the heavy side.  The arc shortens the spring and pulls the shackle away from the equalizer.  This movement spreads the light side axles farther apart.
