Ok, all thanks for help. Trip is over, and all went well. I was looking for an RV park to store RV, and came accross one that would winterize and store for $105 for 10 days. I dropped off RV, put some AF in drains, and let him do his thing. He used air to blow out water and all went well...he got almost all of the water out, except for in toilet.
Made return trip in freezing temps for two of the three days.
Thanks to all for the help and advise...
