Nope, not a H depot airplane propeller...this one eyeballed carefully before using and was straight...my 4 foot level was 4 feet too short for this job.[emoticon]


LOL! And even at $9 each, they didn't get any straighter! [emoticon]

So I cut my mud flaps back to 15" and added a 3/16" board in front of the thick portion of it to form a wedge of sorts. So I got the 7/16" thick at the back for 8" then its 1/4" thick out to the 15".

Thanks for all the replies...

My 2016 GMC long box is 7/16" drop at tailgate when straight edge is run from front of the box.
I need lift for my camper and use two 4'x8' 3/4" sheets of plywood. I shim those with a 1/2" x12" plywood piece across width of box at tailgate.

I have the same crowning issue on my 2016 Ford f350 dually. It's a bother, as it allows for a lot of camper rocking and stress cracks on the tail of the alum bed.

On Ford trucks the bed is deeper at the back, to the top rails. Always makes campers look like they're falling off the back of the truck. :-(

How has the shimming worked for you? Road tested yet?
