Re: New vs. building old one
For reference, my experience:
2010 GMC Ext. Cab. 4.8, 3.23 axle, 2wd, 15.5 city/18.5 hwy.
2000 Silverado V6, 2wd, LB, 3.42 axle, 19 city/24 hwy.
Many 5.3 trucks and suvs, 17-18 city, 21-23 hwy.
I drive carefully, your mileage will vary.
EPA mpg on 4.8 or 5.3 is about 14/18.
