I have always stuffed my sleeping bag, and now quilt, but when I was young, I did fold & roll my tent. I stopped doing that back in the early 80's when I spoke with a manager at the old Eureka Camping Store in Binghamton, NY. Kevin said that folding and rolling the tent meant you typically folded it along the same lines. The problem with that over time a crease would be created in the floor waterproof material. Eventually that would crack and begin to peel, leading to a weak spot for water to infiltrate into the tent. By stuffing it, you'd never have a crease in the same place so it would save on the floor over the life span of the tent. Honestly, I don't know if there's any scientific evidence to back that up but I've been stuffing my tents ever since unless directed otherwise by the tent manufacturer.
That's all for now. Take care and until next time...be well.
