O I have no desire to upgrade anything, the Explorer is just a car the wife runs around town in and we road trip in. I don't even do anything to my pickup's but I have been running stock company rigs in the woods for 20 years and know a stock pickup will go just about everywhere or do anything I'm willing to do in my own pickup. I have never seen the point in wasting money on vehicle mod's when one can only go so fat on public roads. My Dodge Ram hauls up the on ramp and has no problem hitting 80 on the freeway, this Explorer beats the heck out of my old Ram pickup. I have no problem with people spending there money on what they want I just don't spend mine on unneeded cool mods for vehicles, I waist mine on firearms, reloading supplies plus a money pit of a toy hauler.
I do have a Can Am 1000 ATV I did a little suspension work to to get a little more clearance but I tend to ride that thing anywhere and I have a Mud boat with a somewhat modded Muddy Buddy Hyper Drive that I wanted more speed out of to be able and keep a hunting load running in 2 inches of water on top of 6 inches of slop.
