Check bags on GoWesty, I think they have one that opens around three sides.

But also, put the bag on the top before you fill it - then you're loading one item at a time, not trying to lift the full bag.  And turn the long-way zipper towards the poptop, so you can reach stuff from the inside.  I find that's a lot easier than accessing it from the front bumper.

:::Okay . . . thinking out loud here.

:::I stash my long-term camping stuff into a big zippered Cordura bag that

:::So I was thinking . . . most of these items are stored in individual
