I just got my gasser XUV and I looked hard at the diesel !!............I could not see the cost difference for the HP difference. HP is only a couple more ponies in favor of the diesel. The units that I drove before my purchase, the gas seemed more peppy. I know the diesel has more torque, but I am not gonna be hauling heavy loads...............main purpose of mine is pleasure and hunting.

I could not tell much difference driving either the 620i or 850d.
How about fuel consumption? I bet the diesel is much better. I can fill it out of my ranch diesel, so that is nice. If it is like my 2210 tractor i had - it sipped fuel. That is nice when out on the trails, etc - not having to worry about fuel. Of course, more people would have gas if you need it...
Both were dang good rides, but I ultimately went with the gas for the FI as far as starting and with diesel prices here out the roof, I only wanted to feed one diesel.

My only real complaint about my HPX now is cold starts - it sucks It has to warm up some - but I guess it isn't too bad.
In regards to hauling I will post a pic of my gator pulling a trailer of scrap.
