National Interstate (RV) insurance... Comments?

I have NI, no problems here. You can bet the price by a few bux if you look real hard. I had a claim for broken windshield and they took care of it quickly.

Is this the same as GMAC insurance?

We used National Interstate for our 'home policy' on our 5vr when we FTd.
They also insured our truck.
With the full coverage, custom equipment, agreed upon value replacement, medical, vacation interruption etc. no other insurance company could come close on premiums and the coverage.

We had 2 claims over the 7 yrs. One minor and one major........both were handled quickly/no hassles and no rate increases per se. Small increase in premiums due to change of address but that was it.

Great customer service/response. Very happy with them.

I've had them for 10 years. Good service. No problems. Couple of claims.
