I'm a bit of a hypermiler also- hence the Prius which I rarely get to drive. I spend time on clean mpg-a good site. The GM trucks do mild hypermiling very well because when you lift off the gas THERE IS ZERO engine braking at city speeds. When I lift at 35 mph it will gilde in D just as if it is in N, and won't downshift until maybe 23 mph. It makes it great for city hypermiling. A 35 to 28 mph cycle will be about 1/4 mile and 30 seconds or so. One or two cycles is the usual distance between stop lights/signs. I never do motor off glides- not with a 217,000 13 year old vehicle. Besides it strikes me as a bit DANGEROUS. I was never a huge fan of hitch baskets-it makes the rear doors hatch trickier to get to, but the side doors are so big and access so good- especially with second row gone- that we live with it. On the pilot I actually suspended a home made basket from a 4 bike swing out bike rack just so we coyuld open the back hatch relatively easily. It took a bit of doing to suspend the basket(it actually sat on the back bumper/ledge) but it worked ok. On the plus side with a plywood shelf you will have soooooo much storage space you might not really need a hitch basket. In any case carrying stuff on the roof is absolute poison for FE-15.9mpg vs 22 mpg on that Pilot- it would have been the same with the Suburban. At reasonable speeds the Suburbans do pretty well. I think there is just one transmission available-the 6 speed auto- but I think there are several "rear ends" available-maybe 3.07- to 4.11 with the 3.78 being the most popular.I could be wrong about the availability of the rear ends- maybe GM has narrowed the choices now that they have the 6 speed AT- LOTTA GEARS MEANS YOU DON'T REALLY NEED SO MANY DIFFERENT REAR ENDS.
