I am new to camping and I got a 2026 Lanshan tent. I’ve watched lots of videos on how to set it up, and I think I’ve improved, but I still can’t for the life of me get the inner to stop sagging so much. I have tried adjusting the pole (set to 125) and all the stakes/lines (still learning what things are called). The outside looks fine and taut but the inside still sags so much it touches my face.
