I'm modeling M1025 from the early OIF. I have several Blast update sets for it and one of them includes rear shelf full of stowage. I learned the rear shelf was usually bolted directly to the rear hatch, and the stowage was tied using ratchet straps which were routed around the hatch. The M1025 did not have any attachment ponts on the rear hatch as the M1114, hence the ratchet straps.
Now, that could work for larger stowage items like rucksacks, ammo boxes or spare tires. However, the Blast stowage includes all sorts of smaller items (camelback, helmet, etc).

How to secure those to the rear hatch?
