Im planning on adding some sort of roof rack and proably going to intergrate it/connect it to a rack on the back that im planning to have hold a generator. I have a 25 passenger e350 mini bus. Just wondering if anybody has done something like this before or has any ideas to help me figure out how to accomplish this. Im not much of a welder myself but my best friend does it for a living and has agreed to help. Any of you creative types have any ideas on accomplishing this? Thanks.
