The Road Performance Assessment (RPA®)


Road Performance Assessment

Your motorhome's steering, suspension and braking systems are comprised of many different components, each of which must work correctly to ensure proper function of the system as a whole. That’s why we recommend our Road Performance Assessment (RPA®). Developed by Henderson’s Line-Up, the RPA is a systematic, diagnostic 15-mile road test that reveals steering and suspension problems over a variety of road surfaces. You'll ride alongside our technician as your coach drives over highways, curved and narrow roads, sharp turns, even bumps and ruts–they're all included in the RPA to re-produce the very symptoms that you've come to us to solve. At the test's conclusion, we'll perform a detailed inspection of more than 50 points on your coach. These include your air ride suspension (if equipped), tire wear, steering gear, disc brake rotors and pads, shock absorbers, tie rods, idler arms, king pins, ball joints, bushings and much more. Plus:


  • Observe while the technician performs the inspection
  • Get your vehicle weighed at all four corners to determine proper weight distribution
  • Receive a written diagnosis that pinpoints the vehicle's issues
  • Our professional advice on how to rectify any problems–but you make the final decision

Finally, when any repair work is completed, we'll test drive the vehicle one more time, then let you take the wheel to verify the effectiveness of our work.

Trucks, Campers and Travel Trailers/Fifth Wheel Trailers, Too!


The RPA isn't just for big motorhomes with air ride suspension. We can also perform an RPA on your truck and travel trailer or fifth wheel trailer as well. The truck and trailer RPA is similar to the motorhome RPA (above), except we test the rig as a whole, then inspect the truck and trailer individually. In your tow vehicle, we'll inspect the truck suspension, wheel alignment, steering gear, disc brake rotors and pads, tie rods, idler arms, king pins, ball joints, bushings and other components. We'll also check the wheel alignment of your trailer, the bearings and shock absorbers (if equipped) and even inspect your fifth wheel trailer or travel trailer hitch system.
