Insurance Without a Physical Address

Hello all,

I live full time RV.

I’ve been looking for insurance for my F-250 truck and 5th Wheel Camper trailer.

Most companies refuse to insure while I don’t have a physical address, where my truck and camper are housed.

One I found will insure them without a physical address.

One said they’d insure it using the current campground address, and I must call to change my address every time I move to another campground.

 But I thought I’d ask the folks here what they think, what insurance companies are best for full time RV.
