Replace as much as you want (or can afford to). Yes I am a hillbilly, maybe a redneck too. If it was my PUP, AND, the systems cranks up & down correctly (I did say IF IF IF the systems works correctly). I would just buy a few 2X2s and cut them "exactly" the distance from the top of the main frame-to the bottom of the roof (when raised), and place one at each corner when the roof is raised. I cant believe your Coleman doesnt have that already. My old Palamino came with aluminum struts that fit over the legs and under the canvas flaps.
Anyway. Good luck with whatever you choose. Just remember. If a cable breaks, the roof will lower either partway or completely. Cut some wood struts. Its a safety issue
