We switched from GMAC 2 years ago, due to a rate increase from one not uncommon or substantial claim, but mostly also due to their absolutely atrocious customer service. Plus, our venerable service advisor at BCS scowled when told who our RV insurance carrier was - that alone spoke volumes. After some thorough research we went with Allied from Ron at Overland, even though it costs us more overall than GMAC because Allied doesn't offer liability suspension during storage, which our rig spends most of its time in, unfortunately. My wife used to have Nationwide and always had great service, and Allied seems to fit right in under their auspices, with few if any gripes from their insureds.
That said, I'm not beyond moving to Hartford with Roy and David if Allied ups the anty on our annual statement this fall (thanks for the forewarning, Roy). So check Hartford out Linda, but be sure you call Ron Jarvie - as an independent, he can offer a lot of options. I spoke with several agencies and Ron was not only the most personable and enjoyable to converse with, but he also beat the others out on prices for essentially the same policies.
