Alright, I was doing some research on a 2008 Sierra regular cab 2x4, and found that I could get a 4.3 ltr work truck that gets 15 city and 20 highway, or I could get a 4x4 with a 5.3 ltr that gets 15 city and 21 highway. I don't know about you guys, but this simply defies logic.

I can understand that they got some new technology that allows this, but why wouldn't they test it on the smaller engine first or all of the engines.

If anyone owns a truck with a 4.3 or 5.3, don't hold back. I have a year to buy a truck, but right now I am just in the comparison stages

 

The new truck drop 4 cylinders when they arnt needed

 

honestly, since 99 the v8s really dont get much worse than the v6s do... idk... i know a guy with a v6 regular cab and he gets 2 mpg better than my v8 extended cab

 

remember..the v-6 has to work harder..plus the technology difference...its just cheaper to build is all

 

Yeah, I'm thinking if I find the cash to buy a new truck, I'd probably get a regular cab 4wd Silver Bare Bones model with the 5.3. I'm sure you could order em this way, but I have never seen a work truck with something other than a 4.3 or a 4.8

 

I dont think they offer the 5.3 in a regular cab for 07 or 08,just the 4.8 and 4.3.

 

I can get one, I just have to go up to a fancier interior and all that stuff that nobody really needs, they just think they need and never use. CD players are way overrated, all I need is a AM/FM radio. Who needs air conditioning, thats what windows are for, duh, and if you get manual windows you don't even need to worry about rechargeing itLOL.

This is all speculation purely for entertainment value. The newest truck I will probably ever be able to afford in decent shape is a 99 2wd extended cab Sierra of my Grandpa's.
