Progressive (in Colorado) declined to insure our sportsmobile. We have home and auto with them, so that was a bit … disappointing.
I found an insurance agent in Fresno who got us insured for agreed-upon value with Safeco. It's not cheap (~$90 a month), but what can you do?
Here's his contact info:

We got Good Sam roadside insurance after we needed a tow on a forest service road in Wyoming. Apparently (news to us) AAA won't cover towing on a dirt road.
Good Sam does RV insurance as well. Might be worth looking into.
