4X4 here. Because it performs better in winter snows in NH. Only use it to get out of trouble, if needed. When pulling the 5'r, the low range also does seem to be important. Especially for back up a gravel hill into a camp site.
Last truck I had was 4X4 with open rear diff. Unless it was in 4X4, that truck was useless in snow. I do agree the driven front axle aids in steering in the slimey.
I do enjoy Mowermechs stories about pulling hay with 2WD. I also did that on our dairy farm. But when we cut/baled hay it was usually in the mid to late summertime. And the fields were very dry and hard. So why would we need 4X4 for that? Never had any mud to deal with.
