As I mentioned before, we had a Gen1 Raptor with airbags and.....never any issues. With that one we towed our 23' Airstream (about 6,000 lbs and 750 lbs of tongue weight) and before that a 19' Airstream (weighed about 5,000 lbs). Altogether we've towed a little over 40,000 miles so I'd be comfortable saying that I don't think there are too many raptor owners out there with as much towing experience (with a Raptor) as we have.
Anyway, we got the Gen2 when it came out. Before we went ahead and got the airbags again we hitched up the airstream to see how much it would sag. The hope was it wouldn't need the bags, but it dropped the rear about 5", so I went ahead got the airbags installed again. The result is exactly what we needed. With them I am able to get the truck level to the exact height/spot where it was before I hitched up (If I remember correctly it's 42.5" from the ground to the top point of the wheel-well arch). Once that was dialed in I was also able to get our Airstream completely level.
As far as the actual towing ability.......In getting the Gen2 I was, not skeptical, but really hoping that all the numbers of increased horsepower and torque would ACTUALLY equate to (at least) the same tow-ability of the Gen1 Raptor. In the end I can confirm without a doubt that the Gen2 absolutely tows better than the Gen1. It also gets better gas mileage while towing. Even going up and over the passes (and I mean there's some GOOD ONES between Sacramento and Death Valley where we were going), we ended up at 13mpg.
Once last thing. You of course do lose some upwards wheel travel with the airbags. To alleviate this I'm having the airbag mounting brackets re-manufactured. There's a lot of room lost in the ones that they came with and with the news ones I'll gain back about 5.5" of wheel travel. For the offroading we do, that's more than fine and an absolutely fair tradeoff.
