I bought this kit and was very pleased. Not only with the quality but the excellent value for money. For your money you get the eight men, the gun, two boogies and the bike plus shells and boxes. MIne at the moment is half painted and I'm waiting for an idea for a dio to emerge from the vast void in my head.
You sounded quite keen to have the famo towing this. My solution to this would be simple,
have the famo towing the 8t half track with the gun still attached to it. This would make an interesting piece (if not long). You could have lots of figures (the crew of the gun and famo).
The first dio that comes to mind is having it to try and negotiate a tight corner with all the crew trying to give directions.
Cheers
