Traveling to a different state to pick up wine and need advice.

This may be a strange post, but bear with me. There’s this wine that I’m trying to go buy that’s no longer available where I am. I have to fly out to go pick them up, then drive back because they can’t ship it to me, and I’m trying to have an idea of what size U-Haul I would need for the trip. For context, I’m picking up 121 750ml bottles. Also, I don’t drink; no it’s not for anything illegal; and it is for someone but they don’t drink that much at all—it’s more so a keepsake gift.
