RV Tech To Go · Waterford, Michigan
The Michigan RV Year
Everything on an RV runs on one of two clocks: the season, or the calendar month. This is both, laid against the only deadline in Michigan that does not negotiate.

Every month, all year
These two do not care what season it is, and skipping them is what turns a working system into a service call. Both fail from sitting, not from use.
- Run the generator under load, 15 to 30 minutes. Idling does nothing. Turn on the A/C and make it work.
- Fire the Aqua-Hot to full temperature. Even in storage. Diesel left at the nozzle breaks down and clogs it.
