Paz, Thanks again; I broke the one froze tow arm by tapping lightly on the face place end...it broke loose and thus now both sides work fine and I can lock and unlock with the lever arm.
I called blue ox support ... they told me to remove the rubber bellows and spread some lithium-based grease on the moveable part.
Next step is to get the face plate installed on the saturn vue, install brake buddy, wire up lights, .... and we can start towing.
While we have the new, used 2002 holiday rambler vacationer, we decided to keep our f-350/bigfoot for rugged camping...we may even tow the saturn vue but will have to get an extension tow system for that rig:
