Looking at getting a 2002 GMC Sierra 1500 with a 4.8L V8 with 46000 miles. Looks Cherry but really would like the V8 5.3L. Do you think it would make any difference pulling a 6000 lb trailer. Thanks ...
If you are Ok staying close to the 55 speed limit and slowing/downshifting on the hills with some patience to get where you are going... the 4.8 is fine.
If you always need to keep up and feel 55 is dangerous then the 5.3 may not even be enough.
