Bob Bo,
I feel your pain. Dealer told me I had enough truck also. I knew I was close and yes the TV did tow and stop the 5er. The (previous) truck didn't "like" it,but it did it. Being so close to the max I knew I had to upgrade my TV.
The jury is in and has spoken. That is a lot of trailer you have,but you know that.
I think your present TV is new enough that the "sting" (trade up cost to DRW) wont be so bad. Especially since dealers are looking to move new 2018 stock prior to the 2019 inventory arriving, I may be a little behind on this,but I'm sure you will find a deal. Shop around and consider the factory air bag system as well as the tow package options.
One pressing question though. The "weight police" have been mentioned a few times on here. Would they also be known as the "Keystone Cops"?
