Tylus, I'm sure he is talking about light grey seats only, not the carpet. You can get light grey (medium flint) CLOTH seats in a FX4, my truck has them too! But the FX4 carpet only comes in black.

So my earlier possible guess must be true, someone swapped the gauge cluser for a Lariat one.

and he wouldn't have a XLT hybrid like you say, XLT's only come with chrome bumpers and don't have center console shifters.

So he has a monotone Dark Shadow grey FX4 with medium flint (grey) cloth seats (captain chairs with console shifter) and someone put a Lariat gauge cluster in.

by the way, here's a pic of my black FX4 interior with grey seats, his should look the same:

I like how the grey seats match the dash pieces and also my exterior silver color.
