Welcome to the Forums! Late last month, I purchased a new 2018 Ford F150 and financed it through Ford Motor Credit at 0%APR with zero downpayment. I chronicled my experience in this thread. My truck was less expensive than yours; my income and scores were higher, DTI = 16%; and I had no trade-in. But based on my experience, I don't think you'll have a problem getting financing.
That said, I would encourage you to consider waiting a few weeks before visiting the dealerships, for a couple of reasons. First, the financing deals and incentives offered by FMC, GM Finance, and others early in the month and year and relatively weak. I'd suggest waiting a few weeks to see if they renew their 0% financing offers. Judging from past experience, I suspect they will. Also, waiting a few weeks would also allow your FICO scores to rise, which will make your experience with Ford, GM, or Chrysler even easier. Ford pulled my FICO Auto 8 scores from all three credit bureaus, so make sure you know what yours are.
Based on your income, downpayment, trade-in, and credit history, I suspect the truck dealer will be delighted to see you. I've seen folks with a lot less get approved. Your challenge will be to get the best deal you can, meaning combination of price, incentives, rebates, and financing terms. Negotiate, negotiate, negotiate! Do your homework ahead of time so that you know the invoice price for the truck(s) you want. Cargurus, Edmunds, KBB, and other sites will give you all the information you need and even help you find trucks in your area. Last month, I was able to negotiate a sales price for my truck that was 16 percent less than MSRP. You might do even better!
Good luck and keep us posted!
