We had a Chevy Silverado Hybrid for three years. Sounds great but we got rid of it and got a regular jeep with the life time warrentte. Figured they can replace the tranny and engine if they don't live up to what we put it through. We may have to duct tape the windows
but won't have to worry about the driving part of the TV.
The problem with the hybrid was that replacing even the power steering fluid was expensive and had to be ordered from back east. Each time a warning light
came on when we traveled we had to educate the nearest repair place about the hybrid. Many Chevy places said, "we sent a man to the school but this will be the first truck he as ever worked on" As the warrentte ran out it was predicted that we would need $6000 for batterie replacement. Power steering unit was over $900 just for the part. Too many problems even after two years with the new tech.
When we got the Jeep, we actually got better milage on the highway than with the hybrid silverado. About 2 1/2 mpg better on our last California trip of 1800 miles so it really added up. Maybe around town we would have gotten better but we don't usually pull our trailer around town.
My rabbling point is that two years may not be enough of a wait to see how the new trucks preform.
