I had National Interstate Ins. who quit handling MH insurance in December 2017.
I contacted Geico RV, Overland Ins. Safeco, Progressive, Good Sam and Foremost. I found the best price and coverage with Foremost that was recommended by my regular Insurance Agent and I went with them. If you have a regular agent you might check if they handle MH insurance or contact Foremost direct.

The next best but slightly higher was Overland. It all depends on your coverage,year of MH,and what coverage you want.
