Don't go on expedition with a conventional tow bar arrangement, it will act like an anchor when off road in soft ground.
I went for a Southdown tank guard with recovery eye and a removable tow hitch, kill 2 'bird's' with one stone, giving HD tank guard and high level recovery.
I also have a pair of jate rings for bridal strop attachment and an alternative angle if required.
The tank guard strengthens the rear end, bolting to the chassis rails and rear cross member.
If you have a diff guard you may have to grind off a section of the tank guard to allow vertical clearance in testing conditions.
Otherwise you might end up like me with a grinder in a sand storm on your back!
