Can anyone help with winterizing my 1993 pace arrow dp? I lost my husband last year so we had it professionally done but the cost is crazy! The only thing he told me was that the hot water heater does not have a bypass on this model so do I have to fill that up with antifreeze too and pump it throughout the Rv? We had a 5 th wheel camper before so we bypassed the hot water heater. I have 3 water valves but the manual has no information on these. I’ve learned from experience that they need to be closed or you can have a flood! I drive this rig to drag races and really enjoy having it!
