So, 7650lbs tow rating on this thing isn't bad. Now, I'm not sure if that's for the full-zoot Rubicon, or a more 'normal' Sahara. Typically the higher-spec trucks have a higher curb weight, and a resulting lower tow rating.
Either way, 7650lbs is very good for a midsize truck. Class-leading, in fact. A V6 Colorado can do 7000lbs (the diesel can pull 7700lbs), and a Tacoma can pull 6500lbs.
So, this new Gladiator is right up there with the best towing capacity of the mid-sizers.
This thing is really, really cool. I'm sure it will be very very expensive, too. You'll probably be able to buy a VERY nicely equipped Ram for what this thing will cost. BUT, having options is never a bad thing. At this price point, the Ram will fill the 'luxury truck' niche, while the Gladiator will fill the 'bad-ass plaything' niche.
Oh, and I think this Gladiator will be the new Baby of the US Overlanding community. It's available with a diesel (overlanders love small, fuel efficient diesels), and it fixes the biggest shortcomings of using a Wrangler as an overlanding vehicle: Payload capacity.
