I've got a TC Bros. battery box that I'm looking to install. I see in a couple of pics that some people put tabs on the box and bolted the box onto the cross-frame supports. Others have just welded the box straight onto the cross-frame. What's the consensus as to which method is better? I see downsides with both -- with bolt-on, you're looking at a box that could constantly wiggle loose; with weld-on, you've got the box permanently attached to the cross-frame, and while I can't see a reason you'd need to get it off, that's not even an option.
