I'm about to start building my roof rack/ roof top sleeper. Its going to be just like a regular roof rack but with a removable side and a extension that can go in to square tubing and sit level to the rack. It will have adjustable legs to support the extension. I plain on putting a regular tent on top.

My question is what the weight the stock cross bars can support or whats the weight the roof can handle.

I've got no problems with bolting it directly to the roof and if I have to install roof supports inside that wouldn't be a problem.

Here's a quick MS paint sketch.

thanks

 

What i do know is... you want to bolt to your drip edge.. it will hold more then the factory roof rack.. its stronger.. but with a tent and people.. you might want to attatch to both roof and drip edge lol..
