Stick with the Wrangler. It's a lighter tow.
Unless you want to push the towing envelope, or your MH can pull more than the standard 5,000lbs. based on GVWR/GCWR and drawbar rating.
Besides, the Gladiator is just a Wrangler JKU without the rear covered storage area, they turned that into a tiny truck bed, and closed the cab behind the rear seats. And, it's looks like a poor man's Hummer (ugly).
A newer Ford Ranger 4WD would work better, and it's about 300lbs lighter than the "Ugliator". It's actually close to the Wrangler in weight.
