6.4 doesn't have an exhaust brake in OE configuration. You need a programmer to activate the turbo vanes for braking.
If they did, there wouldn't be programmers to activate it.

The tuners change the behavior of the VGT but exhaust braking through the turbo does happen. Ford chose to hide what was happening and when in their setup, so there is confusion. VGT exhaust braking started in the previous generation and is only active in tow/haul mode with no way manually just turn EB on or off. Having a tuner allows more control of the VGT regardless if the transmission is in tow/haul or not.

Emacvay, I stand corrected. Mustn't be a very aggressive profile in OE config, as the ones I've driven I couldn't feel (or hear) it.
That makes sense, and hidden is the right word, as Ford never marketed that capability either that I'm aware of.

If you remember, there were people with VGT's sticking when they were first released. This was mostly the people that drove the trucks empty with tow/haul disabled. My trucks always get 7500-10,000 miles year in tow/haul with a load which I think contributed to no turbo problems. Some of the Ram owners run full exhaust brake all the time - I think they are giving up mileage with this setting but perhaps preventing stuck vanes. Interestingly, some people contribute the head gasket faults on stuck turbo vanes creating too much back pressure.

emcvay,

The exhaust brake on my 2006 F350 6.0 SRW works in tow/haul. It changes the way the motor sounds enough to know that it's more than just a downshift, probably turbo involved as described. Very handy for easing down into King's Canyon with my Wolf Creek : )

My rig is weighted perfectly for my truck in my opinion, and that's the only opinion that has real validity for me. It is the "seat of the pants" meter that makes that determination and I trust it. Panic stops are controlled enough that I am comfortable, though my driving habits are much more conservative when it is loaded. The difference between loaded with empty tanks and full tanks is noticeable, so I usually keep it empty for as much as possible when traveling, but heading out with max fresh water is sometimes unavoidable. Trips home on empty tanks are stress free. I have both types of StableLoads installed and they work very well. My rig actually handles better with my little 8X5 enclosed utility trailer, and full tanks help when high winds are blowing.

My wife and I spent a lot of effort outfitting the camper with lightweight gear. Down sleeping bags, Lexan cutlery, plastic plates and cups, aluminum cookware, almost no books or heavy things like shoes, boots, etc. We managed to keep our extra stuff down to a minimum and try to load any extra items into our trailer when possible (dutch oven, hibachi, canopy, telescopes, ATV, prospecting gear, or whatever else we intend to do). Most of our trips are themed so we don't carry anything unrelated.

Performing due diligence when researching a new camper purchase and matching to an existing truck goes with being responsible, taking what dealers and friends say with a grain of salt is usually smart too. Only you will be saddled with the fallout from an overloaded set up that you may not be happy with, and only you can take steps to fix it. You won't know unless you drive an identical rig beforehand, so lacking that, you are still willing to take the risk - so be it!

As stated before, coming to this forum and asking questions will yield a forest of opinions, and somewhere in those responses might be your answer. It sounds like your head is squarely on your shoulders but it also sounds like you are trying to convince yourself that your numbers will work out okay -- they are what they are. Your experience as a tenured TC owner should count for whether things will work out as you plan, unless "buying fever" has made you blind.

My opinion is worth exactly what you paid for it. I wish you all the best in your experience and will be interested in how it all turns out!

Very knowledgeable and well thought out post Ranger Tim. These are the kind of posts that make these boards great.

For those who hadn't seen it already, I got the 990 and with air bags (barely inflated), stable loads (upper and lower) and the Toyo 4080lbs tires it feels very good!

I may add shocks and a sway bar but for not a super hitch is probably in order and we'll go camping this weekend [emoticon]

No but I'm trusting my current wheels to get the job done.

Did you stop at the scales? Just curious about the weight. It is a nice looking setup.

Posted By: emcvay on 04/04/18 06:37am

Not yet but I will. I'm guessing 4500lbs or so and look forward to finding it.

If I was carrying a camper full time close to the SRW 18" aluminum wheel ratings of 3590x2 per wheel, I would probably get the 19" wheels.

It seems odd to me that, according to the Ford specs in that clicky, both the F250 and the F350 SRW would have a 7000 lbs spring pack with the truck camper package.

Being at the wheel limit of 7180 lbs on the rear axle on an SRW on a long term basis, even if the tires could handle more than that (like the Toyos or the Nitto 285 tires), the major limit there seems to be the wheels.

My rear axle weight with a non-slide camper fully loaded is 6500 lbs. I'm pretty comfortable with it. An additional 1000 lbs go on the front axle.
