"The request documents reveal a number of design flaws in the current fleet that the USPS hopes to address in the next one. The preferred upgrades include: Durable door design—i.e. locks and latches that can "withstand the rigors of the postal duty cycle." Stronger wipers—the fleet's existing windshield wipers evidently experience "fatigue" from all the rain or sleet or even snow that don't keep post-people from getting where they need to go. Crevice elimination—apparently the current trucks have lots of "difficult to access" cracks where letters can accidentally slip and get lost in the mail. Heavy-duty mats—all that stepping in and stepping out takes its toll. Better climate control—Keeping the semi-exposed delivery person comfortable in every season requires a ventilation system that delivers heat or air "in the right quantities to the right body locations." And let's not forget a good cup holder. Supplementary material supplies the specs here: The vehicle shall be equipped with a standard adjustable cup holder. The cup holder shall be within reach of the 5th percentile female and the 95th percentile male in the normal seated operating position. All exposed edges shall be rolled or provided with a radius of curvature to prevent injury. Which raises the question: In what sense was Newman a 95th-percentile male?" - Steve C, Team Marina

I miss the mail jeeps from the 70's and 80's. - Brian Johns

Back then, I wanted to buy a mail jeep -- the post office was selling them, painted primer brown -- and paint it TARDIS blue and put a flashing white light on top. (I also wanted to figure out how to make magnets to put on the doors to make it into a TARDIS for special occasions, but I don't think the printable sheets were available then.) - bentley

"Crevice elimination" still sounds very odd. (From the list of requirements.) - CAJ was here
