Ha, I started looking at some details. We have a really nice pop-up shade structure that we take camping. Steel bars, heavy duty cover, etc. I transport it on the roof rack of the Camry, because it's big.
Apparently it's too big. According to the specs I found online, it 1) won't fit crossways in any of the trucks, 2) won't fit behind the 2nd seat of a regular Expedition, 3) won't fit behind the 2nd seat of an Expedition EL (!), but 4) WILL fit behind the 2nd seat of a Suburban.
Lesson learned: don't buy a shade structure that only folds down to 62" long.
