Some ideas for Gladiators? The Winter 2022 issue of Land Rover Monthly features this HiCap pickup on the cover:
	
	
	
		
		
		
		
	
	
It's outfitted for shooting, and has two drawers in the bed with a nice wooden floor above the drawers.  
	
	
	
		
		
		
		
	
	
The right side drawer is for guns and the other is for drinks.  I never thought guns and alcohol really went together but maybe in the U.K. they do 
 
	
	
	
		
		
		
		
	
	
	
	
	
		
		
		
		
	
	
A couple of interesting things...
On either side of the drawers are power outlets - on the left 240vac outlets (the standard in the U.K, bottom photo) and on the right side (top left photo) are 12v outlets and a battery monitor.
	
	
	
		
		
		
		
	
	
The top left photo above shows a repurposed fuel filler bezel with air and water connections.  It's also visible in the first photo in this post.
The drawers/power outlets could be done in a Gladiator; and what about repurposing a fuel filler bezel the same way on a Wrangler?  I took a quick photo of my dirty JKU and did a little photo editing - driver's side on the left, edited passenger side on the right... I didn't put any connections in the edited bezel, I'll leave those to your imagination:
	
	
	
		
		
		
		
	
	
Wouldn't be hard to mod a fuel filler bezel like this and for protection an aftermarket fuel filler door could be added.  Would be an OEM-looking way to add outside connections to a Wrangler.
