I had an opportunity to test the usable volume of the STS trunk this morning, so I thought I'd post the result. I easily fit 10 bags, each containing 2 cubic ft. of mulch. I probably could have fit one more with a little work but beyond that, the remaining space consisted of all nooks and crannies.
I don't know what the 'regular suspects' might say, but the trunk is easily over 20 cubic feet.
I can attest to that. Travelling back and forth to Florida, I have carted tools, household goods, clothes, you name it. I used all nooks & crannies.
It boggles the mind, the amount of stuff that you can get in there. However, that practice of packing is over for me, as starting this October, we are flying.
IMHO, that's a more practical place for the cooler anyway. (Do use the rear seat belts to secure it. Otherwise, a cooler is quite dangerous in an accident.) When on a road trip and/or touring with my wife, we usually consider the front seating area the living room/office and the back seat the kitchen/pantry. The forward area of the trunk is for seldom used items or the luggage we will be taking into our final destination whereas the the items near that small trunk opening are overnight bags and more frequently needed items.
Curt - You'll notice I do agree on the small opening. At least the trunk lid is squared-off to get that last 4 cubic feet!
