I lean more toward ultracompact (90L+30L Brompton set-up) than ultralight, but they’re closely related. My gravel bike set-up would be ~40lbs before consumables (food, water, fuel) with bike @28lbs (incl. bags, rack, tube/tools, 2lb lock) and camping gear, clothing, gadgets @12lbs. Still pretty comfy with double-wall tent, chair, stove/bar, shower, fan, solar, pedestrian outfits, sandals, evening movies, etc.
