Agreed, as much as materials cost you'll end up spending the same or more compared to just buying one. The only benefit to making your own is you can make it exactly how you want it.I'd imagine there's plans for various type builds for different truck models. I don't see much difference between buying used or building a new one. You either pay for materials and spend some time or you pay for someone else's materials and someone else's time lol.
I just want the slide out deck so I don’t have to unstrap and pull out dog boxes in order to get into coolers and stuff up front. Pop out windows/windoors in the topper would be ideal but aren’t an option.I built one, but only because Decked doesn’t make them for trucks of my 25 year old vintage. I’d have bought theirs otherwise.
Do you need something heavy duty to store tools and such, or more some sliders to carry all your camping junk so you can sleep in the back?
EDIT: I’m a dope, you’re looking for something different than what I thought you were.
