New here and to Ram. Looking at soon ordering a 2021 Big-Horn 2500 4WD (putting together my wish-list now using 2020 info which should be pretty much the same). Trying to not let price get out of control (so easy to keep adding things!). I'm curious about your thoughts on the REAL-LIFE value in the Anti-spin rear differential option ($445)? I don't do any true 4-wheeling. I drive a fair amount on gravel and of course, paved. Can do a bit of around-town snow/ice in the winter but generally if the weather is that bad I try to limit driving the truck but there are times I do need to take it out in the winter. I will tow an RV in the summer months also. Thanks for letting me know if this option is worth getting.
