The only thing my 246B didn't have when we bought it was aircon. However the dealer owned the machine (not Cat) and it had two hours on the clock. We managed to get a 4 in 1 bucket fitted in the deal but the machine was already $9K off the new price. We decided to go without the A/C and have fitted the side windows since. I can get the front door made up no problems. The price of retrofitting A/C with Cat was horrendous. I was quoted $6000.00 AUD for an aftermarket kit which is basically very similar to the Cat kit. (about $4,400.00 US) Its not the hot or cold that bothers me its the rain and the dust. The latter is getting to me as we are coming into summer. I came home last night absolutley covered in dust and the cab of the machine is just orange. On top of this the seat switch has got dust in it and now needs replacing. Does anybody know of a bolt on 12volt A/C unit that could mount on the roof of the cab??. I'd be prepared to import from the states if anybody knows of a reliable unit. TIA.
