What about that new Tornado 3.0L gas turbo inline six? Sounds like a great option for the Gladiator, its supposed to go in the jeep grand cherokee 2022. The new inline six is supposed to be the replacement for the 5.7L V8. Must have some great specs to accomplish that.
I would buy the Mojave just due to the much stronger frame under it than the rest of the Gladiators. This is my preferance due to towing a side by side, and a travel trailer 3500 lb at different times thru the yr.
If you tow and want a gladiator, only buy the Mojave, one frame shop in Az has already straightened 3 of the early JT frames were bent from towing trailers. There is a lot of overlay steel welded to the weak points on the Mojave, way stronger frame.
Coleman Extreme coolers are awesome, mine keeps food cold up to 5-6 days if properly packed and precooled before loading. Under 100 for a 60 qt, and works as well as a super expensive brand cooler.
