Order of Importance of Upgrades

Hey all - I've been lurking for a few weeks and now that I have my 2013 EV on the way I'm trying to plan my attack....and I don't know where to start.

Here's what I know - it's a 2013 with 100 hours on the clock. Custom tires, roof and windshield, far as I know everything else is original equipment.

The only 'functional' mods I for sure want to do is a winch add. That's where I've spent most of my time reading....lots of good info out there on that particular job.

My rig will be used fairly regularly throughout the year - running around the farm property and also trailered a few miles to the hunting property in the fall. So I don't envision the 'sitting on charge unsupervised for weeks' issue being a problem for me. But based on my reading I do think I want to add the watering kit as well as the desulferizer - possibly along with the full maintainer kit, but I'm still up in the air there. I'm 100% positive I want to change the charging algorythm....haven't managed to find the actual instructions on how to do that yet?

What else do these rigs need to have done to them to be bullet proof - relatively speaking?

thanks,

Dale
