Don't forget, 90% of the answers will be from those that have NEVER towed with a late model 1500 and think you need a MDT/HDT to pull anything heavier than a lawn mower trailer. Will the Burb do the job, you bet and it will NOT be a white knuckle experience. We have a 1500(see signature) and routinely tow a 10K trailer here in the mountains of the west with NO problems. there are some limits you may be bumping, but that doesn't mean it won't do what you want. You have done the correct upgrades and I would have NO hesitation doing what you want.
