I've only done mine once in the last 9 seasons. But then again we don't put 1,000 miles a year on ours.
Living in da U.P. of MI, we probably have a few dozen places we can go within 2 hours of the house.
I did find a very useful tool for greasing bearings. The first time I saw one, I used it on the main landing gear wheel bearings on a Cessna.
I liked it so much I bought one for my home tool box.
