Keep in mind that modern temperature gauges do not accurately reflect engine temperatures. They go up to normal and just stay there. It is hard to say how much grill you can block. It depends on too many variables. You don't have big hills in Florida so that is good. I don't know if you plan to tow with your truck. It gets hot there and you may need AC. All of these affect how much grill opening you need. In my experience, towing and a hill in warm weather can max out your cooling system with no grill blocking. I used some temporary blocking and watched temps carefully till I felt comfortable.
