Can i add my truck to my taxes if i am still paying for it?

Having an asset being paid for by a loan is immaterial.  The business use of the vehicle is handled by either using the standard mileage rate   or  the actual expenses + depreciation option.

you can not deduct any of your truck expenses if you are an employee and do to have a side business where the truck is used.
