Congrats on the Super Duty!!!! What a great platform you have!!! I have SSR's on my 2000 TJ and love them. Other than that I am a Toyo MT fan so I guess I won't talk tires with you!!!
I am running an older '88 Northstar pop up on my lifted F150 that has been over some pretty rough stuff and suffered little damage. My fault. Had the top cinched down too tight!!!
I hope to upgrade to an F250 soon. I much prefer the solid front axle!!
As far as pop ups IMHO the FWC are the best for off road. With your 8' box you shouldn't have much trouble locating a sweet used Grandby.
Keep the updates coming!!!!
