Any opinions on 08 GM 1500 with 5.3 engine and 4:10 or 3:73 axle ratio? Found the truck I want but it has the 4:10 axle. Don't pull much but I don't think that one way or another will make much difference with overdrive anyway. Have not taken for a test drive yet so do not know engine rpm. at 70 mph. Does anyone here know?
