It is a brake controller that will work with electric over hydraulic brakes, or just electric brakes. Here is a link. tekonshaa

Dieselgem, Can you give me some information on the P3 Brake controller??? The new X-Aire has electric over hydraulic. We looked at the Escalade Sportster and almost ordered one. It would have been slightly too long for my barn... Glad to see the 450 is doing well... thanks

Sorry, just saw your posting above on the next page... Did you pull your rig with the factory built in controller from Ford. It is suppose to handle electric over hydraulic...

For that much trailer I think I would seriously consider a MDT. Used ones are plentiful and relatively cheep compared to a new diesel anybodies pickup.

I am running the 430 rear which is more than enough to handle the load. Yes, I towed the unit for about 1,500 miles before I switched to the P3 brake controller. I picked the unit up at Tiara RV in Elkhart. The F450 is a MDT. The more I drive the truck the more I like it. I did have one of the bad radiators and had it replaced on a trip to Nashville last month. The disk brakes on the trailer will stop truck and trailer with no problem. Ford is going to omit the 4:88 on the job 3 trucks from what I have been reading on the dieselstop forum. If I had to do it again, I would order the 4:30. The fatory controller is not suppose to handle hydraulic brakes it states it in the manual. It does work but as I said before not as it should. I am pulling too much weight and was not comfortable with it. Some guys are happy with the factory controller.

I feel better about my pulling status from what you say about yours. I have the 4.30 4 wheel drive. Although my truck weighs about 3,000 pounds more than your 450, I think it will still be ok. My Toy Hauler will be a little lighter than your Escalade. I met with my fleet dealer Monday in Fort Worth and discussed the weight issue. I also tracked down some information on the Dana rear end that is in my 550 and I think the same as your 450. It is a Dana S110L. Below is a link to the design spec sheet from Dana which says the rear end is good for GVWR 23,500 lbs. and GCWR 35,000 lbs. So from this, the dealer and I both agree that there is enough fat in the design to handle GCWR 32,000 lbs. even though Ford rates the 4.30 at 26,000 lbs. and 4.88 at 29,000 lbs. (535 Package). I am sure this fat is to cover their butt on users like us pushing beyond the factory specs. As for the integrated brake controller, guess I will look into this P3. I was told the Ford controller would work with the electric over hydraulic but seems it may be not as effective as the after market in this case. I had a Tekonshaa in my one ton dually and was nice controller...

Your truck looks great. The 6.4 is not as fast off the line as my 6.0 was but it does tow a lot better. I think it is interesting that Ford is upping the tow rating on the 4:30. I agree with you based on how this truck handles that there is a fat in the numbers. What are you thinking you CGWR is going to be?

Since I started this discussion, I guess I should do an update. We did buy a 2008 F-450 King Ranch 4x4 with 4:30 rear end. It was a used truck with only 2000 miles on it. The truck was in the shop once for a cooling fan issue, and so far it hasn't re-occured. Have only towed from Moriarty N.M. to Benson Az. but am very impressed with the towing ability of this truck. Fuel mileage not so impressed. 7-8. Also running empty it only goes up to 12-13. Hope it gets better as the miles pile up. As for the trailer we have electric brakes on the Excel Wild Cargo and the factory tow command works very well.

Right now the 550 weighs about 13,000 lbs. Looks like the toy hauler will weigh about 15,500 at delivery. So add 1500 for ATV's and rest of the junk you haul, another 2000 will put me about 32,000 lbs.. Maybe a little lighter but probably not any heavier....

I don't see a concern, I would be comfortable pulling it with your rig.

Safely pulling and stopping a 22,500# 5th wheel is way out of the F-450 Class. At the minium, you need a heavy MDT, or better yet, an HDT. Would you be comfortable loosing your trailer brake controller while desending a 16 mile long 6% grade? It can happen. If you can answer that with a yes, go for it. I was not and would not be. I know I can be in that same spot with my Volvo, and not even know I've lost the controller & trailer brakes. No more damp palms and I can also go up that same hill pulling 22,500# on cruise control at 70 mph if I wish to. All this while getting better fuel mileage towing than a pickup or MDT. While some may call the F-450 & 550 an MDT, it is definately a light duty one or better yet, a heavy duty pickup. Call it what you want. When hauling heavy, only an HDT will put a big grin on your face.

Ray, you really need to examine the trucks before making a decision. The 2008 F450 with the 4:30 rear has been upgraded by for for a CGW of 33,000lbs. I am currently towing a 5er running just over 19,000lbs. The truck has no issue stopping the trailer and likewise the trailer has no issue stopping the truck. I am not cruising up the hills at 70mph. Its more like 60-65 that is the limit I really try to hold. There is no doubt in my mind that a HDT tows more but like all other vehicles they have their limitation. They are cumbersum,and prohibited in a lot of areas (developments). They do not make a good drive vehicle once you arrive at your location. The new Ford trucks are tow monsters, nimble, handle well and are and built to stop the load. I think you will be seeing a lot more of them on the road.
