I had my prior coach (Class C) done through the Escapees Smart Weight program. They actually weigh at the individual wheel locations with and/or without towed vehicle.
On that coach their system was nice because I was able to adjust my air spring pressures to compensate for the weight difference between the left and right rear corners. A 5 psi difference in the air springs made quite an improvement to ride and handling.
I was going to have them do the new coach at the SKP ACRE rally in TN but due to a business commitment we weren't able to attend.
