I've been slowly improving this thing and making it as realistic as I possibly can.
I constructed a Hi-Lift Jack for my custom MATV. It is secured to the hood by two removable hooks I drilled into the hood area. I also added mudflaps, bolt cutters, crowbar, IFF pannels, front side mirrors, and various other repair/maintenance tools.
Not sure where MRAPs or MATVs carry the jack, but I did it this way based on a lifted jeep I saw on the roadway while working the other day.
The jack is made from cut ziptie and cut/trimmed/sanded polystyrene poles, strips, and tubes. Painted by me.
Idea was inspired by this ebay item.
