... I'm taking it to the canvas shop to get a custom enclosure with doors and back windshield. A little plug in heater and next winter its going to be really warm....QUOTE]
When I got my 900, it came with the soft cab kit. Wanting a heater for it, so my FIL could use it in the colder days, I bought the heater kit from my dealer for $350. and installed it myself. It was easy to install and is rated at 20k btu as it runs off the hot water system. My FIL's only complaint is that it makes the cab a little too hot, even in low.
I found out that if you get the dealer to order the kit as a whole good instead of throught the parts dept, it is a lot cheaper. Through parts they wanted over $500 for the kit!
