Ok I had insurance with Blue Sky which the underwriter was RSI Insurance I believe. Like so many others I got the non-renewal notice and my insurance ended today. I got to admit I waited before looking for more insurance cause not looking forward to it at all!!!
I started first working with Blue Sky and their best bet was Nation
Dougherty and Associates was listed on the South Dakota DMV website for RV insurance. I emailed them and got a reply a few minutes ago.

I've never seen anyone reference this company on the forum. FYI.
