Our '03 Hoe has been awesome. The interior kinda sucks despite being a loaded truck, but it is an actual truck that tows things. On a trip to Philadelphia and back we got 17.3mpg, which is really not bad at all for a small building that was carrying 6 people. Normally we have to take two cars for that trip, so it probably ended up cheaper (one car gets 30, the other gets 26-27)
GM needs to put a V6 turbodiesel in the tahoe, something with around 4L displacement. It doesn’t need a heavy-duty tow 20,000lbs sort of diesel, but one that would tow about as well as the 5.3 does and get much better fuel economy.
