Custom Matthews Doorway Dolly, wheels were modified to be hand tightening nuts/bolts. Easy to swap wheels in seconds without tools.

I've tweaked this to fit what we do with it, and recently added a Kessler K-Pod to handle the jib.

Rental includes:
Matthews Doorway Dolly
Doorway wheels (4)
Track wheels (4)
Kessler K-Pod Tripod for jib arm
Proaim Wave Plus 10 foot jib (this is an underrated gem)
12kg fluid head for mounting on the jib / k-pod
4x 8 feet of track (these are extremely long and heavy - you'll need a large SUV or van to transport)
4x Avenger cordura sandbags

This is an excellent rig if you've got the manpower and the setup time (and the truck to haul it - keep this in mind as the tracks are 10 feet when folded up).
