That last BOB is very ideal for me (I think). With little ones in tow I'm not sure that they can carry BOBs so we'll need something that's an all-terrain bag/cart sling over my shoulders like a backpack and pull them and our essentials.

Oh no, that gave me a visual like I'm a water buffalo towing a cart. Hmm I guess I'll have to look for a BOB that would fit my needs. Otherwise, we'll improvise.
