There was a thread not to long ago asking if anyone really worked there truck. My company van was at my mechanic so I had to use my L.
In the bed was 15 - 2x6x16' / 12 - 2x4x12' / 4 - 80 lb. bags of concrete / 2 - skylites / and a screen door.

 

These photos show the reason why I have not lowered it yet. sometimes I just really need it for work.

 

Looks like you may have exceeded the payload capacity.

 

Are u a mason?? Why the concrete? I ask because i also work masonry and sometimes i get stuck using my lightning. It works well but i hate messin it up with crap. They are good trucks though. The payload is a little low but it works!

Vinny, I am in construction - remodeling, additions, trim, and handraill / stairs. The concrete was for a customers deck we were putting a roof on and screening it in. We had to add 3 4x4s because the existing deck didn't have enough to carry the extra weight.
Another job I had 14 bags in the bed (whats the payload capacity 800 lbs) 1120 lbs of concrete. My van was fine then it's just easier to get those bags around in a pickup.

 

Someone dumped a lot of broken concrete on a piece of land I own, so every week I load up about 1,000 pounds worth and slip it into the office dumpster before pick-up day. Really drops the tail and I get flashed for misaimed headlights now that it is dark at drive time. Couple more weeks and it'll be history! (I hope)

The bedliner is holding up well, glad I got it.
