I'm looking at buying a used Tundra double cab and the 2004 SR5 models are in my price range. After doing a little homework, I see the 2005 4.7L engine with the 5 speed auto has the jump in horsepower. It will be a city truck for the most part. But I will be towing a pop-up camper with it occasionally. Will I do okay with the 2004 or should I go with a 2005? After searching here, it looks like the 4 speed 2004 might be best when towing. But, I'm more interested in the day to day performance between the two years. Does one model have less problems than another? Any recommendations would be appreciated.
