Does anyone have new f350 super duty and an older camper?

We have a 2006 Okanagan 9' with slideout on a 2016 F350 (8' box and extended cab -- not crew), and no problem. I wouldn't think there would be much difference between the '16 and '18 F350? Or were planning to get a short box? Don't know what you might encounter there, re older campers.
