I recently added a few new items to the 520 and thought I would share. A 40' light bar from SuperATV, Warn Axon 35-S winch, and a Tractor Supply storage box. The storage box is what I'm most excited about. I scoured through every storage box out there at all price ranges and ironically found the best fit at Tractor Supply for $169.99. Easy universal installation, rugged, and l think looks great. Box can be quickly and easily removed. I have all of my emergency items in it now: first aid kit, Milwaukee air pump, tire plug kit, retractable tow rope, and battery charger. I am going to pick up a second box and mount it on the other side for my beverages. It acts as a cooler as well and even has a drain plug. The box may not be for everyone because the actual storage space is a little small, but it fits my needs perfectly.
