Slide out Beds: buy a kit or build one yourself?

Got a question I was hoping you guys could help me out. I am thinking I want to put a slide out bed tray into my 2011 crew cab 5 ft bed Tacoma. I've been looking around this website but I'm having trouble searching for things. There's two routes I could take one buying a ready-made product and the other one making my own. I'm using the slide out bed tray to hold large crates of camera equipment. It's bulky but not super heavy and I don't know if I need a super heavy duty setup. I'm also not attracted to the idea spending $2,000 on one of these. I'm curious. Is anyone investigated building one on your own? Got some pictures I could see? Thank you so much.

 

Welcome! I'm sure there are other threads, but this has plenty of chatter on the topic ... https://www.tacomaworld.com/threads/have-you-built-bed-storage-drawers.478782/
