I have the GMC sierra with 5.3. (06). I like it alot. Back seat on the ext cab has plenty of room, no one complains sitting back there. I really like the "tow mode" selector in the transmission. Push the tow selector on the gear shift and the shift pattern changes in the automatic transmission. Instead of shifting up at 1500 rpm it will shift up at 2000 to 2500 rpm (depending on torque). It will tow 6000 with no problem. Towed boat from Lake Michigan and travel time, gas milage was not noticably different than when I have made this trip without the boat. Please note that my boat is aluminum and weighs about 3500 lbs. So I do have much more truck than boat. The farm trailer with tractor on it is a different story. It will pull it without hesitation, but I have not pulled it more than 20 miles so I really cannot tell ya how that 6000 lb trailer affects milage.

Ive got a 05 silverado 4x4 5.7 letter gets 19 without and 13.5 with my 19ft ranger, I got the 4x4 not only for the winter but on steep ramps if wet I have seen pick ups that won't come up the ramp until you get 4 or so guys on the back bumper, I can go by myself and not think about it. My friend has a Dodge Ram with a comings diesel and he got a chip for the computer he pulls a 21ft bullet he puts it on cruse and I have seen it go up Hall's Gap and not down shift,he said after the chip he gets better fuel millage, I am going to try a chip for my chevy I have always had chevys but I must say that Dodge diesel is pretty impressive JMO

How did you get an 05 with a 5.7?

There is a fella I know who had a full sized pick up that put all the gas saving gadgets on it and none of it was worth the money when you consider the cost to savings per gallon.
Chips, Exhaust, bed cover air filter and so on....
