Just my $0.02 is I would be a little worried about it leaking a little air out on such a long ride. It would be the same as airing the system up, removing power to your compressor, and taking off on a trip. If your system would not ever leak or need the compressor to come on, no problem. If it did leak a bit, could your straps come loose allowing the truck to move. Not good.
I really don't know "how to", just wanting to throw that out there.
A buddy runs a high end restoration company and finished a $60K restoration on a Maserati Ghibly and had the shipper pick it up to transport back to New York. Next day the shipper called from Colorado and the car had come loose it the trailer during the night. Slammed back and forth enough to crush the nose, rear tail panel, and slightly on the doors. Anyhow, had to do over a 100K to put it back together after ordering a nose from Italy. Bodies are one piece.
