My needs are purely farm work. While I can't say I would NEVER take it on a trail, it would most likely be 'working related' anyway. I've driven the RTV 1140 and I think it would do everything I would need.
The things I want to address are:
Weight: I want to minimize the ruts/depressions I make on my property when I need to work off road.
HP: I don't have a lot of hills, but everything I have is slightly up or slightly down. I don't want to go 'Fred Flintstone' just to get to the barn.
4wd: I have not use for being stuck. End of story.
Diesel: I have OFD delivered for my tractor and I want to make life easy. I also want the power and reliability.
Carrying capacity: This is perhaps one of the biggest reasons I like the 1140. 80% of the time it will likely be in 2 person configuration with a longer bed. But when friends/guests arrive, I'd like the option to move them around the farm easier. Also, we have an old dog, and I don't know how long he will be able to run along side. So, I'd like a seat, but still be able to haul things.
Powered dump: I'm not getting younger but I am getting wiser.
Quality: Nothing I hate more than fixing things which shouldn't be broken.
I don't necessarily forsee it being used for plowing, or towing other than small trailer for specific type of work. But it would be used OFTEN for work hauling. I'd much rather have the 'Utility' of a UTV rather than the 'size' of a truck.
I am not opposed to a Samurai or some such, but other than haul me personally around, it really wouldn't do what I desire without some significant modification.
