The tents of the Arabian rulers that they used when traveling were very luxurious. So it very much depends - the variety in the comforts of (and inside) such structures is as big as in houses. Trucks are usually more limited in the layout and in space, but of course there are multi-million dollar "rolling homes" trucks too.
It might be a tad bit difficult to build a proper tipi (Lakota: thípi) in the bay area, and some damn fool would set the entrance up in the wrong direction anyway.
