This is a pic of a shotfirers 70 series after 120 boosters (thats about 60kg of extremely high explosive) exploded on the tray. Luckily he was out of the vehicle opening a gate. The explosion moved the vehicle 7m forward through the gate, and the shotfirer was unharmed apart from a few cuts & a perforated ear drum (funny that). These vehicles are standard apart from a firewall between the cab & the tray, and no electrics & fuel behind the firewall. Enjoy!
