In any case, unless you believe your pickup and travel trailer combo will stop as quick or quicker than your pickup alone, then the TV IS supplying braking power to the trailer.....and I strongly suspect that the braking power it's supplying is a significant percentage when talking about an emergency stop

The only real difference is an air system vs a hydraulic system. Otherwise the only difference is the physical size of everything.

Nope; your travel trailer does NOT have hydraulic brakes....the semi's brakes are similar in size and type from the truck to the trailer, the contact patch of the tires is equivalent, the brake types are the same between the TV and trailer (unlike the large modern disks on a pick up vs. the old drum brakes on a TT) and the biggest difference; the Semi's brakes are activated the same way (air) between the tractor and trailer whereas most TT's rely on simple time delay or deceleration devices which are inferior and delay the application of the trailer brakes - in the worst case, delaying full activation by several seconds.

IF you had the same tires (size, type and number) on your trailer as your pickup AND you had equivalent large disk brakes AND if they were hydraulically actuated based on the pedal pressure of the tow vehicle, AND the weight of your truck and trailer were equivalent, you'd be much closer to having the trailer provide it's own braking - travel trailer braking systems just aren't even close to the systems used in a pickup truck.

On edit; nevermind, I'll take the hi road.....no need to resort to insults and personal attacks; we're just having a discussion.

I towed a 30 ft Forest River Surveyor for 7 years with over 30,000 miles on it with my Dodger Ram 1500 and with WDH Equalizer Brand. I had no issues and kept speed to 62 MPH maximum. If you are unsure, You made the right decision.

My 5th wheel has four 12" X 2" electric drum brakes
It weighs 14K
I can activate the trailer brakes manually and FEEL it slow truck
Truck brakes stop truck...trailer brakes stop trailer
The 2 working together stop the combo


Taking the high road.......
I hear you there!

I dont know how tight you keep your brakes adjusted, but i do a check every time i pull out. I check my hitch connection, my breakaway, and my brake controller. My brakes are adjusted properly with just a shade of drag. Im usually stopped doing my brake checks, but today i did it at a roll and almost smacked my face off the steering wheel. My brakes work pretty well, like they should. Im out on this conversation if someone feels the need to make personal attacks over what manufacturers state in their guides and what you learn in cdl classes. I have a clean and safe cdl driving record, i dont need to prove myself to someone who hasnt got a clue on the internet.

Interesting discussion on brakes, but we may have wandered. Still ... three questions from me:

What percentage of recreational pullers do you guess have their controlled brakes adjusted properly?

What about trailers under 3000 pounds (or whatever) that don't have controlled brakes?

Just answering the simple question: Can you stop as quickly while towing full as you can unloaded?

Yep, the two working together stop the combo but as I've explained; the trailer brakes do not and cannot provide 100% of the braking for the trailer alone in an emergency stop.....the truck has to help since it has more braking power.

Again, it's relatively easy to prove; if you can do an emergency stop from 60mph in less distance pulling the trailer than the TV alone, then I'm wrong. I think where people get confused is that nobody tests their trailer brakes like that.


cheers,
Dave
