What do you have your Brake Controller set to.

Just purchased a new 2016 Crusader 294RLT fifth wheel dry weight 9033lbs. I was trying to set the brake controller before leaving the parking lot and could not get wheel lock up. I had the new controller set to max 13volts b3. Service department says this is right. I say they are crazy and the trailer brakes need to be adjusted. What setting are you all using for about the same weight trailer?

I have a trailer that's about half that weight, and mine is set to 5.5, b1. Even though your trailer is more than twice as heavy as mine, I don't think you should need the full max gain and boost setting. Perhaps your 5th wheel brakes need adjusting?

Correction, have the dealer adjust them.
It's under warranty.
I wouldn't have left the lot!

When the Brake MFG.assembles the brake assembly the shoes are (Backed Off) so when the Drum is installed there is clearance! NOW between the time that the Drum is installed on the axle and the RV leaves the Factory (SOMEONE) has to adjust the Brakes!! F/R says Dexter-Dexter says F/R,the end result is The DEALER should (Check and Adjust) BEFORE the Owner even shows up for their PDI! We have been through ALL of this very Issue with brakes! Youroo!!

2015 Ram owners may be experiencing the same issue as the OP. Ram went to a new ITBM that uses ABS and and accelerometer to adjust the pulse width modulation to the trailer brakes.

2015 Ram owners with 8k and up trailers are finding they cannot lock up their brakes using the slide bar. Trips to Ram result in being told everything is functioning as intended and it's a trailer issue. The resulting trip to the trailer dealer finds the brakes are properly setup and functioning properly.

My father's 2012 Ram with ITBM locks my brakes no problem. I can't lock my brakes at 10 gain on light or heavy electric.

There is 20+ pages on this and the associated frustration with RAM and the dealerships over on a Ram forum.

I have a Prodigy P3 controller with a much smaller TT (2016 Roo 183). I have this same issue and have posted on the forums about it (month or so ago). The brake controller is maxed out, but I never achieve brake lockup while calibrating per the Prodigy set up procedure. The brakes do engage strongly, but not enough to lock them up. All of the feedback I received suggest that the brakes should be adjusted.

I talked to a tech at Prodigy about the issue and they say that it sounds like the brakes may need to be adjusted, but that they have heard of a few other instances where the TT brakes just don't grab hard enough even on the highest setting (and when the brakes are adjusted properly).

I have adjusted the brakes myself without any change in their performance. I just put the trailer in storage for the winter and will re-visit this again in the spring. My next step will be to get the brakes looked at by the dealer, although they tell me that the brakes were verified to be adjusted properly when I picked up the trailer earlier this year.

I have a 2010 F350 with the Integrated Brake Controller IBC and I run with the gain set at 7 for my 40 5er. I agree you should check the RV brake adjustment first. Just keep in mind that will a IBC (computer) integrated with traction control and anti lock braking systems it is next to impossible to lock up the RV brakes when you are rolling. You will find several threads on this subject. Some of the new Ram TV do have a problem with the voltage being applied to the RV brakes but since you have a GMC that is not your problem. If after you get the RV brakes checked you still have a problem read the voltage on the plug going the brakes of the RV and let us know the reading with max breaking. Hope this help you, but you may not be having any real problem here.

Just a thought. The TV have more advanced antilock break systems on them could this be affecting the TT breaks from locking up. My F350 also dose not lock up the breaks and I have the manufactures trailer system. However I can manually press the button and the trailer will stop the truck and trailer with no issues. Just a thought.

My bc is the Tekonsha p3, I don't have a heavy trailer but I have a smaller trailer and have it set to b2(tandem axle) and at 6.5. At that setting my brakes locked up, but the dealer had to do some work on my trailer brakes to get them to lock up. They have found the front axle brake's wiring was not completely connected from the factory since we bought it new. They also found one ground wire that is causing a short.

So as others stated above, you need the brakes adjusted and especially while its still under warranty. Mine was out of warranty when I discover the issue, which cost me 800 out of pocket for the diagnose and repair. They had to trace out what was causing my brakes not to lock up with the bc.
