I'm pretty nuts about storage on my motors. The onans have relatively small jets, so letting (ethanol) fuel sit in the bowl isn't good. The best winterization is to drain the carb before storing it.

Second best, disconnect the fuel pump and run it dry - make sure you do this with breakers off.

Seafoam and other fuel stabilizers are 3rd in my book... Ethanol fuel really stores poorly. Storing for months, I put Marine sta-bil in the tank and drain the carb.
