When I bought the 835M HVAC Gator I thought I would never use the AC in it. After having the Kubota RTV for 5 years, I thought, well I will take the doors off. I have to say now, the AC is great, my 4 legged friend likes it also. He can't take the heat much anymore so when we go for rides it is in the comfort of AC.
So now I would say the extra cost of the AC when buying the Gator was worth it.
Big Jim what do you think!
