My advice to you having converted from a 5.3 Silverado CC LTZ in back in July would be to simply google 5.3 oil consumption, 5.3 AFM oil problems, and 6L80E shift flare.
I bought my Silvy simiply due to the fact that the price was right and the incentives put GM up over Ford at the time. I put about 50,000 easy miles on the truck and replaced all four door lock acutators, two window regulators, and had the truck in the shop twice for a 1-2 upshift flare (revved up between gears) under light acceleration.
What broke me was at 58k the truck started to enjoy the taste of lube oil. This lube oil consumption was to the tune of 2 qts every 2000 miles. No oil on the dipstick! GM replaced the valve covers with a newly designed cover that would divert the high pressure oil from the AFM actuator in the top end of the motor. The motor still consumed oil, so they installed a shield in the lower end so that the AFM acutator down there did not spray as much oil up towards to bottom of the cyliners. They also chemically shocked the motor to release stuck rings as the cylinders that shut down in V4 mode all had stuck rings allowing the consumption of oil.
Nothing solved the issue. Next step was to tear the motor down and replace the pistons and rings. Not a new motor, but rebuild what I had.
Nope... All done for me.
Now have an 11 F150. It has an EB vs. the 5.0, however could not be happier with it.
Again, don't take my word for it. Google the issues above. There are thousands dealing with these issues.

I am so perplexed at the differences available in the aftermarket... 3.5" full drop suspension lifts, 5.5", 7.5" lifts... All for around the same price... F150s its level it or full lift. No good moderate lifts. Rancho seems to be the best option for a 4" but its expensive as ****

Were you referring to the 5.0?
Reason I ask is I am going to be taking a LONG trip - about 3000 miles at the beginning of next year... I want to get as good of highway mpg as I can and I'm just curious as to how those motors play out for highway mileage. I know my buddy with the 3.5 EB got 26 doing 55mph, normally pulls 23 doing 70mph, and get about 14 in town.... With my lift/tires/etc I get ~16.5 highway, 13 city.... However, when I am cruising at 55 plain flat terrain down at the coast, I get AMAZING mpg.... I pulled 24mpg going from Shallotte to Wilmington NC - about 30 miles at 55 the whole way with a couple sand hills, nothing much. Which is darn good for 35" mud tires and 3.73 gears
(I do have an edge evo, but that doesnt seem to affect mpg much)

the 5.3 in the wifes '08 Avy. Nice ride, and pretty good mileage. Where we had found some non-ethonal gas we ran an entire tank at 80mph and got 18mpg. I love my 5.4, but for some stuff like that it just can't get the mileage.

^ I ran almost a full tank of crappy Cali gas to Vegas and got 18.8mpg going 75-80 mph. The return trip with topped off Nevada gas (still ethanol mixed, but less oxygenates) I got 19.6mpg same speeds. This was over two mountain passes also.

What gets me is the EPA.... I mean how the heck do they come up with those numbers... The silverado is supposed to get 21 hwy and 16 city. The 3.55 gear 5.0 f150 I looked at was rated at 19 and 14 - 16 average.... If that is the case, I can get BETTER, yes BETTER MPG in my current truck with a lift. I would respect an independent reviewer more than the EPA. My truck was supposed to get 18 stock.... Ha, yeah right...

I've driven a few 5.0's and they flat out rock.
I've driven a few 5.3's and they flat out suck.
Friends of mine are currently experiencing the piston slap, oil burning issues.
There is no comparison between these motors, nuff said, close the thread
I'm sure the new chev 5.5 will be quite stout and get great mpg - it has to!

Okay awesome... Yeah, I completely understand about 5.4.... I wish they made a different transmission. I feel like I could get better mpgs out of my truck with a 6 speed. However, I am not getting a new truck just for better mpgs.... If I could get better mpgs, all the better.... I want a solid truck with GOOD mpgs - so basically not pulling 12 mpg on average. Somewhere in the 18mpg range for highway would be great.

as Dewser mentioned, no. It's an EB, but the 5.0's get damn near the same MPG if not a tad better in some situations. I just wanted to put into perspective of how much better Ford's current line-up is over the 5.3L because He (ryanamy) basically did the same style trip and only mustered 18mpg. I will hammer that truck in any performance category and also return better fuel mileage when I want to, same with a 5.0

[QUOTE=wilderthing;4914595]No... Just no. From everything I have seen with toyota's (localy, etc) are they are garbage. If you are going to use a truck as a truck toyota is last on the list. If you want something pretty to drive to the grocery store then you will be fine in one.
I would have to disagree, the 5.7l motor and 4.6l motors are two of the best in the industry for reliability and the 4.6l has years behind it similar to the 5.3. As for the truck being garbage, well from my personal experience and speaking with several dealerships around here the Tundras are what all the oil companies are going to because their ford, chevy, and dodge competitors keep falling apart. Now the only exception to that is the 3/4 ton trucks, but Toyota doesn't make a 3/4ton truck yet. Keep in mind I live in the heart of the oilfield and the trucks around here get beat to hell on a regular basis.
I'm personal buddies with our regional Cable Internet manager, and they use nothing but Ford trucks. Everytime I talk to him he's mentioning how something broke on one of the trucks or the truck was in service for 2 months and the issue never got fixed.

don't go believing the dealership that sells them.
I have not seen one tundra in the oil fields, all 1/2 tons were mostly fords.
