My favorite is cowboy camping under the stars with just a (poly) bag and pad. If weather might be an issue I will set up the tipi. I've been known to set up the tipi and sleep outside of it. If it is too rocky to sleep on the ground I will sleep on the mat in the bed. I do plan for a utility cap eventually.
"cowboy camping under the stars"
Me too. I use a cot that has a "headboard" to hang your hat, etc., on. If it starts raining I just drape the tarp over the "headboard" and my toes and pull it taught. Water runs off and the tarp is off your face. I use an Eena canvas bed roll with 3 inch foam mattress (Beckel Canvas, Portland OR) and that helps keep you dry/warm as well.
One of my friends has a tipi with stove - which we have been forced to use - and a heated space was really really nice on that trip!
All of that said I am saving for a roof rack and a roof tent - for emergency rain shelter overlanding and to make camping more accessible to my family...
