Maybe the real question is where are you going to tow it to and what do you expect to haul with it. I know you a real nit pick, so that means enclosed trailer, you'll be in cardiac arrest with any resulting chips. You have a big boy truck so why short yourself on headroom, you'll be banging your head on the roof and you're already too dizzy. That leaves the length, a couple extra feet won't cost you much and would be easier to get around inside especially if is raining outside when you do your tie down.
Now go buy that. No more discussion. Oh I forget, make sure you add nice bumper rails and mirrors and lights so you can get it in and out by yourself and no damage. Carry on.
