Title says it, who do you use?  Your car / house insurer, Good Sam, others?

Good Sam has been the best rate for me.

I have priced a couple other places.

Fortunately I have never had to use it

Erie for everything.  Home, auto, rv.

Progressive. Bundled with the car and boat.

Had Allstate, never again.

I use Progressive.  They were much better than Good Sam.  Allstate left me on the side of the road without CS after being a customer for20+ years.
I ran over some unavoidable road debris in a construction zone last year and was able to get a claim started immediately.  They proved receptive and worked with Camping World in the state where the problem happened to get us whole.

Progressive. They replaced a crushed RV with no more than the usual hassles.

One more question, if you have had the misfortune to use your insurance.  

What made me rethink my coverage is a vlog where the guy had an incident and no one would cover the damage.  Specifically, instead of a wreak, a section of road construction damaged the frame, axel and some components inside like a fridge.

His insurance bundled with his auto would only cover say a collision or a fire.  

Any thoughts on what company has the best reasonable coverage?

I eluded in my first post that I ran over some road debris, a complete tire retread in bumper to bumper traffic.  The hard rubber ripped the sewer pipe off the bottom of my camper.  We stopped, took pictures, sent them to Progressive and continued on.  Fortunately, we were on the way home so it wasn't as bad as it could have been.  Progressive proceeded immediately with a claim. They were on the problem from the beginning; Camping World not so much.  

As an aside, we traded that camper, a bumper pull, for a 5th wheel, while the trailer was waiting to be repaired.  I never actually knew whether or not the repair was made. Progressive eventually closed the claim, we use them for our 5th wheel with no mention made of the claim.  I always wonder whether some unsuspecting family bought that camper from Camping World without a sewer connection on the bottom.  With Camping World, nothing would surprise me.

Good to know.  Thanks
