My friend Geoff imported this chuckwagon from Australian several years ago. It was designed to fit into a Toyota Land Cruiser 60/62 series vehicle, but probably fits other rigs as well.
You can check out the manufacturer's website at: http://motorcare.com.au/content.php?pageid=1243677038
As you can see from the attached pictures, Geoff had them modify the system to hold two five gallon water dispensers above the table so that they are availabe for use while using the table surface. The dimensions are 281/4" deep, 44 3/4" wide, and 30" tall. The front of the unit folds down for a table with a formica surface. The table measures 23 3/4" by 43 1/2".
It may not be readily apparent from the pics, but this chuckwagon holds eight translucent plastic storage bins, plus the two water dispensers, a metal cutlery drawer, plus room for an ARB/Engels 40 liter refrigerator on a sliding tray. The refrigerator does NOT come with this unit.
For further information, please call Geoff directly. He can be contacted via phone at 509-326-0184. If he isn't there leave a message and he'll get back to you ASAP.
Price: $1,650.00 in Spokane.
