NV and AZ have tax agreements in place. If buying between two states that do not have such agreements in place you'll pay the tax rate of the state you're purchasing in and then pay the difference in your home state when registering. If the purchase state is at a higher rate you won't be refunded the difference.
I'm not sure that's always true. Many states technically charge the tax at the time of registration, rather than the time of sale. If you get a transit permit (or whatever they call it), you usually don't have to pay tax, just the relatively nominal fee for the transit permit. You do, of course, have to pay tax in your home state when you register the unit.
At least, that's the standard practice for motor vehicles as I understand it. I think trailers are generally treated in the same manner. Vehicle taxes are usually not sales taxes, strictly speaking, but rather use taxes, collected in the state where the vehicle is registered.
(This is exactly what I did when I bought my motorhome. I paid the gentleman I bought it from, got the title signed over, and took that paperwork to the NH DMV office. The NH DMV took my $10 or $20 and gave me a transit permit, a short term temporary registration. I then drove my motorhome back to Vermont, went to the VT DMV, and paid tax and registration fees to get proper plates. I would also have gotten a freshly minted title at that time had it been a little newer. Vermont and some of the other New England states do not issue titles for vehicles over fifteen years old.)
