If you decide that you don't want to make one, but would like to save on the cost of a Blue Ridge Overland Gear 4Runner Attic, let me know. I'd sell my nearly new one for $80 shipped to move up to a Raingler full-length net.

I think [MENTION=137794]JasonKoko[/MENTION] has a mod like this..
I have a Blue Ridge. Works fine except it sags way to low. And no it is not the contents weight.
I replaced the hooks in back cargo area with some d-rings. I have some pics and info starting at about here in my mod thread.
I actually just ordered some d rings (more like v rings) from amazon. And then I used Velcro cable ties on the hand holds in the back. Ordered a cargo net from amazon and all works perfect. Total cost was less than $20 for everything and works great
Go to amazon history
copy paste invoice with part numbers
