Insurance for late model Conversions 2016-2019

I am a recent member of POG trying to purchase a coach in the years 2016 to 2019 and have been quoted prices of $17,000. to @22,000. per year for Agreed Amount and $10,000. to $12,000. for ACV and $5,000.00 to $6,000.00 for Max of $1 Million and must self insure for balance ACV. This seems pretty steep to me but I have not found anyone commenting about these prices on the site. It appears that there are only a couple of companies still willing to insure coaches with a value of over 1 million. Does anyone have any knowledge about insurine coaches within this age and price bracket? I appreciate any input!
