Buying new truck but what truck is the better deal?

I assume these are 6.0 liter trucks. I don't think that motor really cares about the miles, but the price on the '15 should be in the lower 30's in my view for an SLE with those miles. All things being equal, I think the interior of the '15 and the exterior handle on the excab would make that truck more desirable. However the price is too high in my view for that trim level with those miles.
