If you don't have a problem making them a little smaller in diameter, I have the fix. I do this for my Beef Stick, which is kinda, sorta like a summer sausage.
You form logs about 1.5" to 2" in diameter. I season with coarse pepper, then wrap in clear wrap. Tie off one end and twist to make the wrap tight, then tie off, use a twisty band or a zip tie.

I let mine refrigerate for 24 hours and they will firm up. The small diameter works better than a large diameter. Carefully unwrap and put on a rack and move to the smoker. Touch up the black pepper if needed. I smoke mine to 155° (you mentioned you added cure right?) . You could lightly spray with oil after an hour or two if you like.

These guys look like there is a casing, but there is not, it's more of an edible rind. After you chill them down I'd wrap in foil for the camping trip.
