I think mine may be a Napier as well. If I remember I'll check the brand. With a full size bed, you can also take normal mattresses (Full). I've also *gasp* driven with it up short distances. It tolerates 30-35mph just fine, so it's convenient for short relocation.

And yeah, Kodiak is the top-end, but I have no experience to say how well they handle wind while driving. I presume they would do as well or better. On the other hand, they are probably heavier too.
