4.8 vs 5.3 questions and thoughts?

[C&C Chevy]

Hey, I normally don't post here. Well, never, actually. I'm an 80's guy.

...anyway.. my dad has been looking at some crew cabs of this era and the 07's and newer. He was asking me about the 4.8 vs. 5.3 engines. We both know that the 5.3 is a good all-around engine when it comes to power, MPG's and reliability. But, he's telling me that there just aren't alot of used crew's available with 5.3's and that he's finding more 4.8's out there in used car land. And they're cheaper too. I know nothing about the 4.8's and come to you guys for you thoughts on the 2 engines. Keep in mind, he doesn't haul anything but the occasional couch or chair.

I guess he's worried about the quality and durability of the 4.8's since you never hear much about them. Any thoughts and/or personal experiences are welcome! Thanks!
