I posted about a month ago concerning buying a camper. As I said in my old thread I did buy it. It's 26 foot and weighs 5200 pounds. My ecoboost is rated to 7200 says in the door jamp but a few others on here said I was rated to tow 8200. Well I'm camping on my 2nd trip right now. First time pulling it i was kind of nervous since I have never towed anything really. I have the weight distribution kit in my camper but I guess I didn't have the chain links up far enough and the truck seemed to be kind of floaty feeling. But on the way home I managed to get the chain up another link and it was better. So yesterday when I hooked the camper up I made sure I put on the 4th link with 3 links hanging. Truck did pretty good. The ecoboost I must say is impressive. Had some pretty good hills to go up and I could accelerate going up them. But my biggest concern is the trailer brakes. Sometimes when I break for a stop light and get down to 10 mph I feel like a pulsating in the brakes. Seems better when I take brake out of the trailer but it I liked the way the trailer stopped better the way I had it. Suggestions?

 

Maybe double check the gain on the brake controller - you may have too much or too little. I think there is a procedure in the owner's manual on how to set it up correctly.

This seems to be what everyone says to do to set the gain:

The problem is I don't have the ford controller. It's a aftermarket one

 

check on you tube to set up lots of vids there

 

When my Aftermarket Controller was set 'too' high for conditions, I could feel a shudder when stopping. I set the Controller to just skid on our Gravel Driveway. I then reduce power just a curly hair's worth. On Asphalt , that provides me max stopping power just short of skidding. Water in Tanks, etc., adds Trailer weight fast. I set up each/every Tow.

 

I would recommend looking into installing the OE ford trailer brake controller. It integrates into all the vehicle systems including ABS, trailer sway control, instrumentation, etc.

As for floating or wallowing going down the road; what tires are you running? My FX4 came with crap "P" rated tires which suck for towing. I quickly switched to E-rated tires and run 60lbs in them and the ride is so much better when pulling a load. No more floating around.

 

I would certainly recommend checking the tires as xcntrk has suggested. Not only are the original tires junk, but they may be a bit unsafe towing with the sidewalls wallowing around. The E rated ones will do you better. When you're not towing, you can lessen the air pressure a bit to make the ride a little more soft.

Yeah I'm still using the factory good years. Not sure if there p's or not. But I'm running 35 psi all the way around

 

I have a factory controller for sale here:

I guarantee that the floating feeling you are getting is the result of your 35 psi Goodyears. I towed our TT thousands of miles with them before switchiing to my 60 psi TRUCK tires (Michelin LTX MS 2's).
You will not believe the difference once you equip your truck with the proper tires for towing. No wallowing, no counter steering when traffic passes you, better mpg, just straight down the road like there's no TT behind you.
