Is this possible?

Hey everyone - very similar post to the latest one in this forum by mine is more tax related.

My wife and I are Canadian citizens but we want to purchase an RV in the US and leave it down there for the winters. We will be going to Palm Springs/Indio area for 6 months each year. We would never bring it back to Canada ... just leave it in storage during the summer months.

Here is the key thing - I want to try to avoid paying as much sales tax on the RV purchase as possible. Would that mean purchasing from a dealer in Arizona and having them deliver it to me in CA (out of state purchase would be tax exempt I was told). Would CA then allow me to plate it or would I have to pay CA sales taxes when registering it? Should I get it shipped to another state nearby with lower taxes and register it there to pay the least amount? If so, which state?

The RV we are looking at is 78K + 12% tax here in Canada = $87K CAD. The same rig is $52KUSD x 1.3exchange = $67K CAD before taxes. So at the minimum its an $11K savings - significantly more if there is a way to pay less sales tax.

Thanks for any help you can give! I have searched everywhere and so happy to have found this forum :) Hoping someone can help me out!
