We are going into a transition phase, where next year we hope to be going on the road for what I've coiued 'Permanent Part Time Full Timing'... Off for two or three month trips, then back to the home base to check on family. So we will be putting on many more miles over the years ahead, is teh plan.
I posted on another thread, taht I'm thinking of changing to Syn oil in the ISL next service, and then going to a yearl/miles change of oil filter and oil analysis. On the generator, will also shift to syn (help on cooling I hope), but due to the small amount of oil, change yearly.
All other services will be based upon time/miles per the normal schedule.
I'll also add an opinion, that I think many need to stay on the yearly schedule, if they are low miles per year, with periods of 'winter down time'. We get our coach out every 4-6 weeks for a run. Generator fired up, AC's running, and get everything up to proper temperatures and run things long enough to work out any moisture. Some in the 'winter down time' can't do this, and yearly service is probably the right thing to do... But, we all may have different opinions
Best to all, be safe, have fun,
