License a small bus

[Deefar]

Hello, I am new here and hope someone can help. I have a 2008 Chevy exp small bus, 20 passengers. On the title weight is 6,609lbs. I am having problems getting insurance for personal or commercial use. Can the title be changed to a van? And how would I do that? Unless there is something else that can be done. I want to take out all but 2 sears, there are 5 on each side. I am not looking to turn this into a camper/RV, just want it for personal use. I live in upstate NY outside of Buffalo. Any help/suggestions would be greatly appreciated. Thank you.
