As first time RVers we just took our 2013 3170DS Sunseeker out for our maiden voyage, highway driving was smooth, averaged about 8 MPG. RV was winterized at pickup, hooked up at the campground, flushed all lines until pink was gone, took WH off bypass, installed anode rod, everything fired up fine, hot water, generator, frig, freezer, stove. Potty was broken in properly.
Dumped Black and Grey w/o problems, rinsing well between tanks. Had three great days, crisp evenings were enjoyable in a warm RV with a beverage of choice.
Once home, expecting freezing temps, we opened low point (little drainage, since we ran off city water and didn't fill FW tank, HW tank was bypassed and drained at the campground) used 30 PSI compressed air to clear all water sources in the RV, connected suction tube to water pump, drew about 2 gallons of RV antifreeze through all water taps and allowed them to drain a bit into the traps. Poured a bit more into each trap and toilet. Cleaned up excess antifreeze in sinks and bowls. Not anticipating travel for a month or so, did I miss anything winterizing? Should I leave a little antifreeze sitting in the toilet?
Did I mention that this is a hoot, can't wait for the next trip.
BTW thanks to all for all the info and responses prior to this trip.
