My truck is an 06 and yes I measured on a concrete slab in my garage. Funny thing is yesterday I completed the AS add a leaf and it only raised the back about an inch on a measuring tape, but seems like more visually. I am happy now though the truck looks nice and right now it's loaded with half a bed of firewood, a generator, two coolers full of beer and 5 gallons of gas and the tail end isn't facing down, matter of fact, those items in my bed didn't seem to do much at all in terms of squatting the rear. Now let's see what my camper does to it once I hook it up with the EQ hitch.

 

Has anyone ever posted about how to adjust your headlights? It seems to me like it would be a pain. I didn't find it in the manual, but maybe I didn't look hard enough.
