Spacing on Roo?
Sorry that the Anderson levelers did not work out for you. I may face the same thing. I will pick up my new Roo 23IKSS pretty soon since the weather appears to be cooperating finally here in northern Ohio. I was seriously considering the Anderson levelers and have seen how they need to be trimmed, etc sometimes. Could you post a reference measurement (tire to tire, center lines, etc) from your Roo where they did not work? It might avoid me going down the same route you did.
Not having taken possession yet I don't know my spacing.
BTW, what are your plans for leveling now?
