I have a 2010 Ram Quad Cab 4x4 Hemi with 3.55 gears, I am towing a 2011 Keystone Passport GT Ultra Lite which weighs about 7,000lbs. I installed the OEM trailer brake controller and everything seems to work fine except when I am at low speeds between 1 and about 30 mph that brakes seem to surge a lot when I barely push the truck brakes. If I'm going over 30mph and I apply adequate brakes the read out says like 30 and it seems normal until it drops to lower speeds and then again starts to surge. Also if I am stopped at a light and go to take off it takes a second or two after my foot is off the pedal for the trailer brakes to release.

Anyone have these issues at all? Or know how to fix them? Any help is much appreciated!

 

use the plus/minus to adjust bias. Here how mine is set. 2.5 I tow a 14k 5th wheel.

 

I have taken it all the way down to 0.0 and they still grab/surge at the low speeds.

 

my controller had 2 settings, i think bias and an amplification adjustment. you set 1 and then adjust the other, if it doesn't work back off the 1st 1 and retest.

 

My controller is the OEM Controller with the just the one +/- setting. I have tried to take it all the way down to 0.0 but it still does the same thing.

 

Could the hill assist setting on the evic cause that? Mine does it too.

 

Getting off track, I currently pull a 4200lb TT that is closer to 5300 fully loaded. It tows great even here in the 10,000 foot elevations. I am now looking at a 6800lbB TT (empty weight) and wondering how well it would tow with my 1500. How does your 1500 Hemi do with the 7000lb trailer, is that empty weight or loaded? Thanks

 

I didn't even think about that, I will give it a try the next time we take the TT out and see if it does anything for it. Thanks for the suggestion.

 

Well my truck is rated (from what the dodge sheet says) for about 8500lbs towing. The TT weighs about 7,000-7,200lbs loaded, I haven't been able to get it weighed to know for sure.

The first time I took it out it seemed to want to push the back end of the truck around a little, I didn't have the sway bar on for this trip and this was the first time using the equalizer bars as well. The next time I moved up 1 or 2 links on the bars and used the sway bar as well and we towed it from Colorado Springs to Ouray up over Monarch Pass which is 7 miles up....UP...UP! The TT did a whole lot better this trip as well as on the way home. Right as we were getting back to the Springs we hit a storm and the winds were crazy, a gust would hit the TT and make my butt pucker but the sway bar did it's job and never let it go anywhere. (All this was just after seeing an F-150 on it's side and his trailer in the ditch on highway 50). The truck did great now that I know which links to put the equalizer bars on and use the sway bar.

 

Thank you for the replay, good info. I also live in the Springs and know that route very well. I am rated to 9200LBs towing capacity without even using my tuner. I also had to up the preload on my WDH 2 notches after going from my 04 RAM to the 09, other than that the weight is NO problem I can still do 65 up the HWY 24 grade all the way into Divide with no problems.. EVERY time I get held up going up these 10,000 foot passes it is because I am stuck behind some F-150 with the 5.4L huffing and puffing and doing like 20MPH. I think I will be fine then going 6 feet longer and about 1100lbs heavier. Power is not an issue on the new RAMS, I just don't want to be using up all my rated tow capacity - as you know these mountains here will tear up the unprepared and underpowered. In the summer I am sure you have seen the grade on I-70 near the Eisenhower tunnel looks like a battlefield with all the broken down steaming vehicles along the shoulder. If you can tow up here, you can tow anywhere. Thanks again, see ya on the roads
