I don't have a trailer hitch on my truck but perhaps this picture will help you decide it the mounting bracket on this step would interfere with your hitch. I've indicated the bracket in red in this photo. It uses the bed hold down bolt and an oval hole in the frame forward of that frame tab...

I ended up having to have the step installed by a shop. I gave up after two batteries on my Dewalt 20v impact driver couldn't get the bed hold down bolt to budge. Your mileage may vary.
The shop took about 20 minutes, including reading the install instructions.
I'm very happy...

I contacted Amp Research to see if they will be offering their "BedStep" for the new Ranger (had seen one on an F150). Was told they had no plans to make one.
I then found Bestop's "TrekStep"
It was shown as out of stock when I ordered it last week.
They said they should...
