I am a better to have and not need…I have a 20 yo Ram 1500 with the Hemi. It is 4wd. I do not have locking rear. Wish I did. I probably wouldn’t use 4wd half as much.
I tow a Blackjack 224 and you know it’s back there. Just got it so I haven’t launched or recovered it yet. But I picked it up in TX, towed it 11hrs. 18ft Kenner before that…of course, not an issue.
