If you're considering the XX40 series, definitely go with at least the 7040 as it has limited slip front end and there's not much size or weight difference between the 5040-7040. The time to make that choice is now when the price difference between the models is relatively small. I started out looking at the 6040 but was quickly convinced the 7040 was the way to go at a minimal cost difference. The real question is the cab, whether you feel it justifies the substantial extra cost. And definitely go with the hydraulic shuttle. Yes, maneuverability might be an issue in limited situations, but how often will it be? Think the consensus is generally people regret not going large enough rather than too large. The cab issue is something I can't help you with as I like being out in the open air. Where are you located? good luck bb
