That's as good a way as any by a DIYer. About all I would add is that you should use a method for a stand off to compensate for tire bulges which are not always uniform.
What I will be doing soon as I too have a tire wearing is use a length of 1" square tubing I have and drill and tap 4 holes to match the wheel flats at the center line. Those tapped holes will each have a bolt locked by a lock nut at equal height. This contraption will be set up at that center line and measured agaonst each wheel. Camber - same kind of gadget.
Amazing that RV manufacturers feel that they can use the same 3" axle tube, 5200 through 7000 pound series with only hubs and bearings different. And on trailers from about 7000 to 15-16000 or more pounds.
