20 footer:
18's are real common. I've seen some crazy pics on here with guys loading crew cabs on 'em, nothing but props for those guys - you make do with whatcha got - but it was too balls-out for me. I got the 20, but even then a crew is gonna hang off about a foot.
And no, that's not my towin' rig. That's the day I bought the trailer.
