Richard,
I gave links to PROFESSIONAL RV alignment shops that have equipment you have probably never touched. Just because you have never worked in a well equipped shop is no reason to try to discredit shops that have an outstanding reputation in the RV world. Perhaps you guys should stick with small vehicles and leave the
RV's and trucks to the PROFESSIONALS. Even the FMCA link mentioned how the rear axle can be adjusted on a gas coach but I'm sure that you and Dodge guy have years of experience back when a lot of things were not possible. Time marches on and has left the two of you behind.
