Yeah about 10" of leg room if I remember right.
I don't know the measurements but yeah at least 10" by sitting in them. The back seats also recline.
Ava's feet hit my seat when she's in her car seat and that's with my seat about halfway up...I usually have it pretty much all the way back.
Also thinking about a 2010 Powerwagon, they are between my cab size and the Megacabs.
