Nice set up if your target isn’t shooting back at you....
I’d take a lower profile in the bed of the truck, otherwise.
That is why I have a 5/16” plate of 540BHN steel screwed to the bed side of one of my trucks’ tailgates.
Weighs about 90 lb. The truck rides better when empty and I get a little arm curl action when operating it.
I had to use a torch to cut the holes for the screws. No drilling! Lol
The set up is for varmints at extended range.... I shoot a little long rang comp and would be happy to teach her a few things. Might be fun to sit down with good 1K Rifles and see what the lady can do.
