Lance and 2015 GM 2500HD

I had to raise mine about an inch to clear the bed rails. I have a 2011 chevy with a 04 lance.

If you run a tape measure from the floor of the bed to the top of the bed rail; what's it read?

Well, I have about five or six inches cab clearance, and my TC was laying right on the rail before I stacked it on the decking ... I couldn't even squeeze a sheet of paper in there.

So, regardless of what Lance says, in the generalized statements - I believe those dimensions are inaccurate - I'm sitting here looking right at my truck with the camper on it. One thing too, the bed rails have those composite protectors on as well, so that could be 1/2 inch - not sure. But this is just a heads-up to look at it before you damage your TC accidentally.

Now it has a 3/8" bed mat and a 5/4 decking, and it appears right about at one inch clearance. It's raining, so will check tomorrow again, and mention it here if different - unlikely tho'. It just pays to check it ... :) :)

Cab clearance 1 1/2"
bed rails 1/2" per Lance

Ok
