Check out my thread: Getting ready for the grand.
Homemade aluminum table that doubles as a ramp, first ever Grover hanger that provides easy access and carries the Grover outside the frame. I also made a aluminum fire pan that served us well on that Grand trip, aluminum side boards, light weight really strong. I made a huge dry box for carrying all the misc. stuff that's hard to pack, sits under my flip seat holds the stove, fire pan, repair kit, major medical, dart board, bocce balls, hand wash stations.
Working with aluminum is really cool, it welds pretty easy after you get a little experience, easy to grind and fix a bad bead, cuts with carbide Blades on any
Wood chop saw.
