First time buying a vehicle, can someone help? (need advice)

Ok, so before I get into the details I am 22 years old with a credit score of about 715–730. I have a outstanding debt of about 10k (student loans) and a DTI (debt to income) of about 15% . I make about 90k-100k a year, have had my job for about a year, and am looking at trucks anywhere from 30k-40ish. I plan to put down 15–20% on any truck I may get, and plan to buy from a dealership.

So I’m just curious to peoples opinions and personal experiences with purchasing a new/used vehicle. I have little or no experience when it comes to this don’t want to get denied by the bank for a loan haha Thanks! :)
