Wondering if anyone has some advice for putting together a platform for standing on top of my Toyota 4Runner. I have rigged up a great canoe carrier, 7 feet wide and holds two canoes, but I need to set up something new that will provide a shooting platform for when I need a little different perspective.
The factory racks are painfully narrow, somewhere around 32-36 inches (less than 1 meter) and probably only 4 feet long (just over a meter). I would like to have the platform slightly over sized for that sized base, maybe 6 or 8 inches (15-20 cm) wider and 10-15 inches longer.
I'm able to design and put this together myself, although I would have to outsource any steel work. Mostly wondering what materials would be both light and able to handle fairly high humidity here in North Carolina.
I'm accepting both proven and possibly ridiculous ideas. :P
