On my way home from Colorado, driving down the road, I got the service start stop soon message. My 21 Mojave has been on a maintainer almost since new when not being driven. The truck is 3 years and a half month old. These batteries are crap. I will be replacing both and fully charging them...
I have that bumper and winch on my Mojave. I did not need spacers but I did re route the wires out the side of the winch to get clearance at the grille.
