Semi-nomadic if I remember correctly, and they had some trouble with Islamic scholars, they insisted on only praying 4 times a day (because of the differencies in the length of the day between summer and winter) and used co-gender saunas, and was quite stubborn about keeping it that way. My guess are that if they go full settled, they will begin to produce alcohol and pork, and tell anyone whom insist it's un-Islamic to go to Hell.
Of course if we see them spread in the Volga-basin, we may see Scandinavians settle the Norvograd area (through they may adopt the "Finnish" language). While Ukraine stay a weird mix of "Tartars", Magyars, Alans, Goths and Greeks until someone end up dominating.
