The BEST way to install a safety plus is----install the Safe-T-Plus, get it as close to neutral as you can, then have the Motorhome alignment done. When they start the alignment they loosen the u bolts on the Safe-T- Plus. When they align the RV, when they get it to spec, they then tighten the Safe-T-Plus u bolts and the system is now set to trac true and straight. The bad thing about a Safe-T-Plus is, if you do not get it perfect when you install it will pull to one side. AND, if you do have an alignment problem it will make it worse. Doug
