I don't have pics on this PC, but I recently added the cooler/jerry can rack to my Proto Fab rear bumper. It was a great space saver in getting the cooler out of the Bronco and I can now bring a bigger cooler. Also, it makes geting in and out of the cooler easier. I snagged a pic from their website.
I have 2 toolboxed behind the rear seat, then bungee a couple of backpacks on top of those with all the family supplies...diapers, wipes, kid snacks, etc.
One of my next projects is to finish my half doors. I am going to close off the gap for the window, then cut out part of the inside of the door to create a big hollow part to hold more stuff.
When wheling with the family space is definitely a premium.
