I don't know your personal reasons for not wanting to deal with GoodSam but I have been insured with my motorhomes through them for years with excellent results. I originally had GMAC and found that excellent. Then I had Allied and this past weekend they (Good Sam) saved me over $350 per year by switching me to National General which was formally GMAC. National General specializes in RV insurance, has full-timers coverage, optional full replacement value, storage option which saves you when you are not actively using the RV by paring down the coverage and personal belongings insurance up to $3000 for full replacement value.
I had claims with GMAC on a previous RV and they were handled without problem and expeditiously. AS you may know GMAC has been around for over 60 years and had an excellent financial strength rating before they changed their name.
