I am seriously considering getting rid of my 03. Even with the 4.3 and 5 speed I am making an average of 14 miles per gallon. I know they had some hybrids that are rated at 15-19 with the 5.3 and that doesn't seem bad at all.... plus i could get the extra cab for more storage/louder stereo. Do any of you guys have a hybrid? Or have you heard anything about them good or bad? I have heard nothing.
