You problem is most likely just lifter noise. This is common with a lot of Ford engines with self adjusting lifters. Although lifter noise is bothersome it doesn't pose a serious problem. Unless your engine starts to miss or your gas mileage drops way off lifter noise is just an annoying problem.
I would recommend that you add some Sea Foam Engine Treatment($6-$8) to your oil. This is not an oil treatment it's more of an engine cleaner. If this works you'll need to add it every 2nd or 3rd oil change.
If this doesn't take care of the problem then depending on your engine you may have adjustable rockers that would allow you to remedy the problem. If not, your options are limited to living with it or replacing the lifters and possibly other valve train parts.

Likely an exhaust heat shield. When the SUV is cold - after sitting for 4+ hours - crawl under the vehicle and see if any of the shields are loose that cover the exhaust pipes. If they are you can use sheet metal screws screwed into the shield and against the exhaust pipeto 'wedge' the shield so it doesn't move.
