I've never measured my trucks temp, but I just replaced my entire cooling system, and the thermostat I installed was a 180 degree. That's what was in it before...although it appears that for several years it probably wasn't working to well, if at all.

I can watch the temp rise until the thermostat opens, then it drops back down a needle width or so. So I would say mine normally runs at about 165?? That sounds on the cool side, but it's just a guess.
