Folding bike paired with folding trailer - specifically, Brompton M6R and Burley Travoy. You'll have ~150L/100lbs hauling capacity, with the ability to wheel everything indoors behind you like wheeled airline luggage (bike covered if you like). You'll be able store everything securely and weather protected inside your tent. And, if you're in decent shape (since max total would be ~130lbs), you could backpack/carry everything in one shot for short distances, eg, staircases, narrow doorways/hallways, into knarly woods for stealth camping, and use public transport/subways. Everything is quick release and quick folding and would take ~1min to convert between riding/walking/rolling-luggage modes.
