Under Body Boxes
 

I am looking for some used underbody boxes... 24" tall, 24" deep. My truck is in Tacoma, so the closer to that location the better. Would like to get 4 boxes matching total to 16+ feet

If you are going to string the boxes together would you not be better off getting two 8 footers? I just had boxes custom made for my truck and the price was better than sourcing regular boxes plus they fit my particular application. Mine were 6foot 8in each with spring notches and front tapers to fit my deck.

Good luck. Every time I've seen somebody with used boxes they seem to want about as much as new ones, which are expensive as you know.

I don't know what kind of project you have going there, but for that many boxes have you considered building them your self all in one unit exactly the size you need? Compartment doors are not that expensive to have built to your order already framed with hinges and latches, and if you get some at the surplus in about the size you need they are downright cheap. I paid $15 each for my rv compartment doors at Bontrager's, but you really need to be able to go there and pick through the surplus stuff.

I have seen a couple listings for boxes on ebay, but they are overpriced and in the wrong area... Maybe I will do more checking for custom built boxes.. Thanks for your advice

I built my own for a fraction of the cost and just the right size. Its not as hard as you might think.

The others are probably right about building your own. Maybe build the box and purchase the door. Check some the RV surplus places for deals on doors.
