RTT-21's are a three section wheeled transporters used to transport dangerous liquids through rough terrain. They are named as a 'Caterpillar', beacuse they are usually painted green and articulated chassis makes that its move is similar to catterpillar's.

The cabin is taked from one of the 4 Juniors sets, 4653

It has an awful pattern on front, so I rotated it on the back. It looked better, but there was no room for whole minifig. But his half fits perfectly ;)

The tanks for transportnig those dangerous liquids are made from white Airtanks:

With and without load:

Each section have a pendular suspension, that provides great stability when vehicle is moving through obstacles.

Intresting creation, I think the colour code goes great with it. Just wondering what are the canasters on the(I don't mean what there for) I've never seen them before. Anyway I love it name

A fascinating work with an interesting use of a 4 Juniors part and these air tanks.

The vehicle looks very smooth and beautiful and the suspension´s very nice too.
