I looked high and low for an arm rest because it was driving me INSANE not having a place to put my arm.... Then I found this...
I was skeptical at first, but when I got it in it was extremely well made. And made by hand. It's got alot of weight to it and has an under strap that runs under the seat to secure it in place.
The great part is, my kid sits on top of it, with his seat belt on it and he can see over the dash now lol. Best thing I've bought for my truck aside from the 4.88's.
