I did not need to run the rod all that much... it was in great shape and not dry or rusted at all- I did wipe it down and apply axle bearing grease.
Not going to powder coat the inside although I am sure that would have helped in not having all that crud build up on the inside. I need to just make sure to (as the mfgr states) to fully extend and retract the jacks at least once a year to distribute the grease inside and as well to keep an eye on the general condition of the jacks.
I am just very surprised at how quick the rust build up cause a total failure of the operation- I sensed it last year and noted to myself that I need to give some lovin' to the jacks and the only time I needed to raise the camper this year it would not work!
Glad I got it working without needing to buy new.
