Undercover Swing Case

[milkmaster]

Those undercover swing cases are available from Undercover probably a lot cheaper than GMC.  I had them on my 2018 F150.  They come for either side of the truck bed.  I had them on my F150 for a time.  They were handy for hold straps and other misc items.  I eventually took mine out because I like to install a piece of wood across the bed in the slots to keep coolers or gas cans from flying around the back on short trips.  The swing cases are in the way for that piece of wood.  The swing cases are easy to install and do lock in case you don't have a cover over your bed.  Lock your tailgate and the case cant be swung back to come off the hinges and be stolen.  They are very sturdy if the need suits you.

I had one in my FX4, had to repair it twice due to cracking along the back side where it latches to the side of the bed (I repaired with a support brace and nuts, bolts & washers).  It also broke at the hinge (the pin) and had to replace that which was pricey because it required you to purchase the entire mounting assembly.  I had about 50-75lbs worth of gear (tools straps, etc., etc..) in it.  Overall I was disappointed in the build and material quality!

 

Obviously, I don't plan to get one for the trail boss!
