I love reading these insurance threads to see the wide range of rates that people pay. There’s no apple to apples here at all, because of all the difference factors that go into insurance rates.
I use multiple insurance companies because despite what they say, bundling them all with the same company does not save money. They obviously want you to think it does in order to get more business from you. You must shop around. Progressive is low priced for me for some policies I have, but not on the motorhome. The current premium, not at Progressive, is $216 a year for full coverage on a 2020 motorhome, ACV not to exceed $83,000. It costs less to insure a new motorhome than an older compact car. Apparently motorhome claims frequencies are low.
I suggest getting rate quotes for rate comparison from at least six different companies, more if you want to get the best deal.
