RE: Montana plates for tax purpose To all you folks that have had a bad experience getting an LLC or using Montana services to save money on your taxes, have I got news for you! We registered our RV in Alaska (where there are no personal taxes.) It was only 3 days and we had our new plates and registration. We are traveling alot and havent been pulled over once. We have been telling friends and aquaintances about this and they have done it without any problems. I think you all are using the wrong state! I think the price to do this up there was cheaper because we didn't have to do anything except set up a trust on line. Took about 10 minutes.
