I've use the Commander for some small utility towing, but this set-up should be right around the max specced. Sorry I didn't get to scale the whole set up, but the tongue weight I figured at 630+[see scale confession below]
I pulled the A-piller cover for temporary mounting of brake controller and a trans temp gauge [I can't find a pic of the gauge now, and I took it back off for the wife's daily commute]
I forgot to fully document the weight distributing hitch install, but here is a pic of one of the several tongue weight checks [I know I cheated by using the jack instead of at the ball, but I went a little light, and figured it was better than not measuring at all].
I spent lots of time adjusting spring bar pre-loads and hitch heights, but I ended up with a trailer level to within 1/4 inch front to rear, a tow vehicle with a total ride height change [front and rear added together] of 1 1/2 inches and the most pleasant towing experience I have ever had including the first day in the snow storm.
I chose to put the trans temp sender on the line to the cooler for monetering temperatures at their hottest. Never a concern at these ambient temps. That's 5*F incase it's too blurry to read.
Pulling out of gas stations in 80* weather provided temps of 210* but quickly cooled back to 150* once underway. I'll add a fan for the cooler this summer before deciding if a larger cooler is necessary.
Here is a good shot back at home 1800 miles later
