Is there a chance that air leaking on one side faster than the other side in bags could cause that much sway say 60 and 75 psi for the bags

Close but the data noted above does not fall within the ranges specified in this forum. R camber at 0 should be 1/8 to 1/2 positive and the camber offset (R to L) at 1/2 is higher than the specified 1/4-3/8 degree. Doesn't seem to me that the small differences would make that much of a difference but people report it does.

What reason would a alignment shop not go to the exact specs if it could make that much difference I assumed that his equiptment told him where it needed to be they had the specs off the forum but you are saying they should be even closer than they are and no reason not to be

The specs off this forum are not the specs an alignment shop would have since they are not the same as those specified by Ford. Ford's specs have a larger range and tolerance to the settings and THE Forum specs provide criteria on cross camber and caster settings. Thus the specs provided in the Forum are within the Ford tolerances so you would not be contrary to Ford.

Within a few miles I knew my 2012 was not right. However when I took it to an alignment shop they test drove it first and said what is your concern since it drives as good or better than most Ford based RVs they have worked on. We checked it and it was within Ford specs but I said there has to be a way to make it better. I worked with the tech and came up with some adjustments (didn't know about the Forum specs that came out later) which by some skill but mostly luck made a world of difference. Turns out the changes we made were similar to the Forum specs.

Long answer but that's why. The twin I beam suspension used is strong but was designed in the 50s and technology has improved. When Ford swaps over to the new transit style it should handle better and be less finicky. Ford is the only game in town for the big Class Cs so they have no reason to engineer the replacement and it's only for a few thousand sales.

I did have the specs from the forum but the man thought the handling would not change much from where he was at and was trying to keep the tire wear down but will re adjust to specs next week and add a blue Ox track bar also if it is in by then at this point I don't care as much about tire wear

For some reason some owners have to add after market bars etc to get it handling to their liking while others are lucky and can get it handling car like with stock parts. I really want to swap out my steel wheels with aluminum for better looks and unsprung weight reduction but am concerned that I might mess up my great handling since the wheel offset/backspacing is slightly different. Hope you have good luck with your changes and can get your unit feeling the way you want it.

I owned a 2005 ford excursion and spent a lot of money trying to get it to trac correctly.There is very few shops know how to work on strait axal fords.I have owned many motor homes class a and c with ford platforms and had many proplems with handling. This time I bought a class C 32 foot with a chevrolet 4500 And it handles like a car.it was also abought 2000 dollars less than ford v10. Ford knows they have proplems with there suspension and does nothing abought it .my new coachmen came with air bags and trackbars and indipendit front suspension.
