Sorry to hear about your conundrum. I am a firm believer in preventive maintenance. Personally I use a "white Board" to handle all my mechanical maintenance for all my vehicles, trailers, jet ski's, etc. Basically tracking lube data, hours and due status. I use a spreadsheet with all the "systems" and items I want to check on the left column, and I do a 52 week schedule. Some things I check pre-trip, some things monthly, some weekly, and post-trip. This way I can make sure that I am looking at everything throughout the year and noting problems before they become disasters.
