I may feel your pain and pace this year, the woman wants to take the Tahoe and I have agreed against my better judgement. The Dodge with the Hemi is way better IMO but she says the captains chairs in the Tahoe are more comfy. With the truck last year I set the cruise at 75 and let her roll, barely ever shifted out of OD and averaged 15.7 mpg. There's no way in hell this Tahoe will do that.
