Thanks for the input people.
I must take the Hummer for a few reasons:
The wife doesn't pack - she moves, and the Vette won't haul all that stuff.
The Jeep is just not that much fun on long hiway runs.
The dock is 340 miles away and a cab would cost more than the Hummer!!
I can drive there faster than flying with all the security and lines and transfers. (tried it once - just once)
So I'll drive the Hummer and pull a few fuses and relays out and hope it is still there when we get back!
