I'd check our sway bar end link rubber. Mine were squeeking really bad, was embarrassing. I loosed them up and injected grease around the bar with a needle fitting on my grease gun and fixed it right up.
If you search "2 Girls Garage Jeep 5th Wheel" they did an episode where they made it happen. Beds gotta come off obviously, I believe someone makes a kit.
I traded a full-size Ford for my Gladiator, never looked back. Yeah I can barely tow my boat now but that's not everyday and like you said, once you take the top and doors off it's 100percent worth it.
