"...The most impressive new rolling gun case is made by Do-All Outdoors, the company which manufactures the Do-All Trap, an extraordinarily innovative, value-engineered product in its own rite. The Do-All Outdoor company designed a virtually indestructible series of gun cases they call “Flight Proof Gun Cases.” These extraordinarily durable cases feature low profile wheels, ball corners, rubber feet, spring-loaded recessed handles, tongue-in-groove seals, and pad-lockable butterfly latches. The two-gun case I tested positively exuded durability....
For an expedition, especially if I am sharing a gun case with a companion, I want the most invincible rolling gun case I can find, such as the Do-All Flight Proof gun case. I carry with me a pair of nylon straps, so I can attach my duffel bag to the gun case, using it as a hand truck of sorts. Since the firearms must be inspected upon departure anyhow, it is relatively convenient to access a stand-alone case, rather than having to remove the gun case from a duffel bag..."
