Solved - Geico RV Insurance has no issue with consignment sale lot.
I checked with 7 companies, found only Geico RV policy allows continued coverage if placed at a consignment lot.FYI - Not able to cover on a consignment lot were: Nationwide, Good Sam, Progressive, Invest America/Nevada, Miller/Oregon & Roamly (note: Roamly could have quoted if I was not leaving at a Nevada lot)
