Food Truck Depreciation or Monthly lease

Hi experts! 

We ordered a Food Truck late 2020 and received it in Jan 2021; the food truck business started mid-2021.  The sale cost was $29,000.  We paid $10K as a down payment (3 installments in 2020) and what we were able to quaify  to finance the remaing $19K was a Lease Agreement paying a monthly fee for 40 months.  The Lease agreement allows to  purchae the food truck at the end of the term for $2K.     How should I consider the food truck acquisition, an asset to depreciate or take the monthly fee as a expense deduction? Should I consider the $10K down payment different to the lease payments?

Thanks
