Agoaliemom,
We have 5000 miles on our 213. With 20000 on yours, if the alignment seems good, you are probably fine. The nuts that were loose on each tierod are easy to see from front of truck. Ours were two big silverish nuts that butt together on the 1 in. (approx.) diameter black/gray-ish rod that slants downward to connect to the lower side of each front wheel.
On retiring. I am looking forward to the 'unknown and wide open' aspect of being retired. It appears to me that retirement can be dynamic and freeing! I am a big follower of Robert Pirsig's (from St. Paul, MN) thinking on Dynamic Quality, which, in his second book, Lila, he describes as the cause of the evolution of things towards ever-greater freedom.
His most famous and first book is 'Zen and the Art of Motorcycle Maintenance.' If R-Vision would only follow Pirsig's thinking on Quality, we would have a whole different experience with our RVs.
