In today's big transports, it should roll right in and be tied down with come-along chains.
We often transported jeeps and small trucks in our C-123s and C-119s and they were relatively small airplanes compared to today. The first really big carrier was the C-124 with 17,440 cubic inches of supercharged engines (14,000 hp). The big transports of today dwarf the C-124 and can easily swallow something the size of an Airstream.
The Loadmaster will position the Airstream and other cargo for the best center of gravity of the aircraft.
