We knew we wouldn't be able to get the cover from research. The thing is we have a large barrel for diesel for our tractor and we use a lot of diesel just from the gator so we didn't want to have to buy gas all the time. Plus the gas gator uses more fuel. I dont think it is absolutely necessary as Ive gone through lots of mud and crossed a creek several times but I do see the use in having it. As for the hitch yes it is 2 inches our dealer custom did it for us Im pretty sure it wasn't any more expensive.
