I think the newer SRW trucks like the F350 will do better with a hard side TC without a basement or 7.5 wide camper like a NorthStar Igloo, Capri Retreat, Bundutec Bunduvry can get it 7 or 7.5 foot wide.
Hard side without a basement your outside sidewall is around 10.5/10.8 feet high sitting on the truck. Be sitting at 11 foot or just over that with an AC on the roof.
I do think no matter how big your hard side TC is on a SRW...you will be at a stand still here in Kansas when the wind wants to blow 60 mph gust.
That is another reason I'm looking at pop ups. I don't want to be a sitting duck if the wind wants to blow at 50/60 mph gust. 40 mph might stop you in your tracks with a SRW and a hard side. Lot to think about when using a SRW and a hard side TC
