Splash guards and toolbox install

[gemarsh]

Replaced narrow splash guards on the front and back wheelwells using what probably is for the at4. Also went ahead Friday and mounted the crossover toolbox on the carbon pro bed. Used 3m's super grip version of velcro. Went off road in some pasture with new snow over the weekend and it didn't budge. 

 

I'll cross some ditches at an angle and put it thru some flexing this spring.
