This is a great resource.
I think if it becomes a sticky, you should be even handed as well as selective in who you include (or exclude) in your lists of vendors for various gear.
Example: in the Retail: Armor/Winches ... etc you should include companies like BudBuilt and Shrockworks, two well respected vendors whose quality equipment graces many of the builds on this site.
With respect to "selective," vendors such as WabFab, who have horrendous reputations for customer service, should not be promoted at all.
I'm ok with this. The links I included are ones I came across while I was researching potential 4Runners I was interested in and what could or couldn't be done to them. I've owned my current 4Runner about three weeks and I don't know all of the companies or their reputation at this point. Posts like yours and the ones above will help make this a better thread.
I added Budbuilt and Shrockworks, I'll remove wabfab if more people think they shouldn't be there. I added another vendor, sonoran steel. I sent an email to sonoran steel about one of their products and got an email response in about an hour. Steve there said all of his product photos were on third gens, but he would ask a local guy to get him some shots of his product on the 4th gen if I wanted. That's a pretty indication of their business IMO.
