Your welcome, glad to try and help. If you have not, bring this Lippert file along with you. It may help some too.
I am heading out camping and internet signal is questionable. Will be off line for a while. EMD_Driver may be able to help pending what you run into. His slide had a simailr issue last year and we ended up retiming the slave drive and the last I knew it was doing OK.
The thing we and you do not know is, what was done before you bought the camper? Did some one try and adjust it and maybe, do the wrong adjustment? Good question... So I gave you what to look for on both sides.
