Hi, Dale I have done the same for Trip to Ohio checking the rig. The cable has to much slack in it and if not attached on way out to the release latch will just flex the cable wire tubing.

So I release the latch by placing my long fingers

through top front vent opening and feel up just to the right on release latch and pull cable wire to release latch.

Once the latch is released you may have to dress the cable wire over the locking bolt, but with practice its no problem. I find I'm always forgetting to pull release for hood

and most of the time I just use my hand to release from outside.
Have a good time and safe trip.
