Check with Onan prior to adding methanol to propane
I see the Solera does have a propane LP generator. If you decide to add methanol, please check with Onan first as you don't want to mess it up. I have heard also that the light bulb in the compartment will also keep it warm enough not to freeze up but doesn't solve the issue permanently. If you want more information on the freeze up. check the RV.net forum and do a search for propane problem and go back more than 12 months as this is a cold weather issue.
