I purchased a 2021 new motorhome in 2021 and want to see if I can get any of the State and local taxes back.

In 2021 I purchased a new motorhome in Arizona. I usually take Standard deductions in past years and using now Turbo Tax Deluxe.
The state tax was over $8,000 and local city tax was over $3,000
Must I itemize deductions to try and get some of these taxes back?
Normally I use standard deductions in past years and have not had any changes in my gross income.
I usually using standard deduction never owe any additional tax to FEDs or to State.
I do not live in it and use it just a few months a year.

So the question is can I gain anything from itemizing or can I still get some of this back using standard deductions.
