height? / good wide folding stool for pop up truck camper

I've had the above HF step for over 10 years even though I have banged it up pretty good. The work platform from Werner is also something I own when I need more height and it has also held up well.

My F250 with 33" tall 275/70R18 tires was under 7' at the top of the cab. With my 6'+ height and long arms, I might be able to reach pop camper latches without a stool but it would make tucking in the sides difficult when retracting the roof.
