1.no need for lavatories that's what the bush is for.
2.most of the hunting I found was road hunting, trackers will ride up top looking for game, it is also quite fun. With hunters sitting inside the truck it takes longer when an animal is spotted to get ready.
3. Charging rhinos and elephants!! Really??? They only charge if the babies are threatened, if so just shoot them. No amount of armor will proctect you!
4. You will also need a roller across the bottom of the bed and a rear winch. Plus leaf spring rated for like 3tons(not kidding)
I am a modest gentleman, and the privacy potty is necessary: at no point during any hunt would I venture away more than a half mile from the parked convoy on foot: I don't want to squat in the bush and have a spitting cobra bite me on the ass
