Do you have a question about the Tarptent StratoSpire Li and is the answer not in the manual?
Spread canopy floor-side down, prepare stakes, and set trekking poles to 125cm/49in.
Stake one vestibule door side taut, leave cording, insert pole handle-first through vent into grommet.
Pull canopy ridgeline out, insert second pole through other vent, stake opposite door corners taut.
Restake corners for a rectangle shape, ensure flat sides and taut ridgeline.
Pull out Pitchloc strut corners firmly, stake through plastic loop, and tighten fabric with line tighteners.
Unzip doors, adjust floor straps for even tension, and attach apex guylines for ridgeline tension.
Stake guylines separately midway between door stakes for optimal ridgeline tension.
Unclip interior from fly, spread on ground, stake all 4 corners on the black floor side.
Retie apex guylines to door zipper hooks and insert pole tips into elastic loops.
Stake the two trekking poles to tension the interior canopy structure.
Use tension straps to lower effective height and widen floor for two wide sleeping pads.
