I believe in being very diligent with lubrication, changing belts, monitoring and changing tires, etc. However on alignment I would not change it if you are happy with the way it drives and the tires are wearing well.
What you might consider doing is have the alignment measured and get a printed report to keep as a base line. In the future you can use this to compare to new measurements to see if anything has changed.
X2 on this advice.
I owned a 1997 Class C that we bought new. All was good for the first ~15K miles and then all of a sudden the front tires start to wear terribly. I knew something was wrong and took to a shop in Florida, he told me that this was common on a Ford chassis. After getting it fixed no problem, sold it after ~70K miles.
We bought a 2002 DP and when I inspected I there was a problem due to tire wear pattern and a shimmy in the front when I drove it 800 miles home. I knew I'd need new front tires so I had 2 new tires installed and immediately took it to an alignment shop recommended by Buddy Greggs. Have since put +50K miles on without a problem, no tire wear at all and drives straight and true.
If tires are wearing good, no wondering or vibration in the front I wouldn't touch it.
