Although I have no experience with that particular unit, one only has to look at the specs to know that it's beyond the capability of a 3/4-ton single rear wheel truck - especially one that's 9 or 10 years old (GVWRs for trucks have increased over the years). The GVWR of the trailer is 16,000 lbs. Using 23% of that for an estimated loaded pin weight would be 3,680 lbs. As is the case with most 3/4-ton trucks, you would run out of rear axle capacity long before you run out of total towing capacity. Neither airbags nor any other aftermarket modification can change the GVWR, tire, or rear axle ratings for your truck. Those are determined by the design engineers and printed on the weights and capacities label on the driver's door frame. You will find that this is one of the most-often discussed topics on ALL of the RV forums - use the search functions.
