Fulltimer Insurance

I went through Miller RV Insurance.

They aren't tied to any insurer which gives you lots of options.

I'd also suggest a Personal Liability (or "umbrella") policy since you're selling your house.

I had National Interstate for years. No claims. They kept raising my rates significantly each year and finally just got too expensive for us.

Check out National Interstate & Bluesky

We used National Interstate for 7 yrs FT.
Complete home owners style policy PLUS.
They specialize in RV coverage and FTrs
2 claims during that 7yrs. 1 minor/1 major----both handled quickly, efficiently with follow ups and no hassles. No increase in premiums.

Heard good things about Bluesky also
