Kind of comical seeing all the posts citing the truck's brakes when pulling a large trailer. The trailer brakes stop the trailer anmd pull backwards on the tow vehicle if adjusted properly. Having the truck's brakes stop the trailer is asking for a jacknife to happen! The trailer MUST pull backward on the truck when braking! Different when hauling a truck camper as it has no axle nor brakes so the truck brakes must stop both.
That's funny or is it comical? :h
On their own the brakes on my current 3500HD dually are designed to stop a 13,000 pound truck and the last truck I had was a 2010 2500HD where the brakes on it were designed to stop a 9,200 pound truck. Theoretically the dually is 29% better.
At the controller I setup the properly adjusted trailer brakes to the point just before lockup with either truck. I feel that familiar tug whenever I step on the brake pedal in either truck/trailer combo.
Except that the dually has better stopping ability so from a practicable standpoint.... yes that combo does stop better than it did when the over loaded 3/4 ton pulled the same trailer. This with the trailer pulling backwards on the TV.
I think travelnutz gave some excellent advice and allow me to add my experience.
My last truck (2500 HD) and a bit lighter 5er than yours. Quoting from CRS memory but once I added in the hitch weight, people, gear & fuel including a transfer flow tank I was over the GVWR of the truck by about a 1000 pounds. Truck was near the RAWR of 6000 pounds which is pretty much the limits for the two E rated tires.
Truck pulled it well but.... Stability wasn't good especially in a side wind. Air bags helped but still not where I liked..
I upgraded to a dually where it made a night and day difference in stability and braking ability... Peace of mind that I'm way under on the TV capacity is nice too.
Recently we stayed in this nice RV Park in our Zephyr DP... However, when we set up in our assigned spot there were some branches on a tree that were contacting the left side of our coach. I could have backed up except if I did that our bedroom slide would be beside our neighbour's fire pit!
So I asked the office what our options were where they agreed backing up beside the fire pit would be least desirable so they offered to come right over and trim the branches away...
Everything was good again except for this guy three sites over that was drinking wine and taking pictures of our DP! I hope he wasn't thinking of stealing my Harley?!?!?!
