That's good info. Here are the tires I'd consider, in the order they finished in CR's very recent 2011 test of all season light truck tires. All of these are made in the United States according to Tire Rack's database.
+ Continental CrossContact LX20
+ Michelin Latitude Tour HP
+ General Grabber HTS
In CR's testing, all of these tested "Excellent" for both wet and dry braking, and "Very Good" and "Good" for snow traction and ice braking respectively. All three also scored "Very Good" and "Excellent" for ride and noise respectively. All had "Good" tread life.
Differences are the Continental got "Very Good" for handling and the others got "Good". The Michelin got "Very Good" for rolling resistance and the others got "Good". The Michelin placed ahead of the General because of the better rolling resistance score. The Continental placed ahead of both of the others because of the better handling score.
Your OEM Bridgestone Dueler H/L 400 tires were not tested, but the similar Bridgestone Dueler H/L Alenza was, and it finished mid-pack at best. Any of these three will be a positive improvement over your Bridgestones.
Hope this helps.
