I have a 2009 F250 XLT Crew Cab, I use it to tow my work trailer and fifth wheel RV on a gooseneck. It seems as if the truck handles the fifth wheel okay. Fifth wheel is around 13000lbs. I realize I am over the payload with that pin weight. Does the F350 have a stronger rear axle giving it a higher payload capasity, as the rear axle in an F350 is rated for around 1000lbs higher? If I could replace the rear axle would this increase the payload on the truck? I am not interested in purchasing an F350 at all, I have replaced every compenent on this truck other than the engine and chasis, too far in it financially to want to give it up, as it is a great truck.

only the F350 dually has a bigger axle the SRW 350 is the same (minus spring codes and gearing options) and the only variable is a 1 inch taller rear block to raise the rear more so it can droop more lol ..

Ford plays a lot of number games and one reason there is an F250 and F350 is to get around some rules

Payload only matters to DMV... even if you put the axle under it the 14 year old frame, brakes, ect will all still be under rated.

Time for a bigger truck

Fifth wheel is around 13000lbs.

An F250 should be able to handle this. I think Ford states @14,000 max for 5th wheel with an F250. Why don't you add the HD springs and overloads like I did?

Exactly. Also if your not towing commerical and just RV'ing no cop gives a rats butt. Not once in my entire 37 year career have I seen a Texas DOT Trooper scale an RV load.

My diesel mechanic looked into this for me and he essentially told me the same thing you are saying- The only difference in the SRW '09 250 and 350 are the rear leafs and 4.10 ratio vs the 3.55. He is going to get on the spring kit for me before long. I just had the bed off a few months ago for a misfueling incident, should have done it then hahah. I appreciate the feedback.

 

[ZMANN]

The bed off wouldn't help much IMO you unbolt them and slide them out on top of the axle ,, even with my 2 post lift I would probably do this on the ground
so what do you do with RV glass ? I have a broken RV window

 

[WiseRVGlass]

We do any and all RV Glass. Custom window panes to match, windshields, showers, mirrors, ect. [email protected]

I have a broken RV window

What RV are you towing. And,,,how the heck did you break an RV window????

 

[krazyk]

SRW '09 250 and 350 are the rear leafs and 4.10 ratio vs the 3.55

On a 2009 the F250 and F350 SRW probably both have 3:73 ratios. The Sterling differential in both are the same. A 2009 F350 DRW will have a Dana 80 with a 4:10 ratio (in most cases).

not towing any RV's but hit a tree limb .. lol

 

[krazyk]

Well that's cool, and your not even worried about the frame breaking in half like the famous Dodge meme.

 

[ZMANN]

I am not worried but it is not that I don't check the frame occasionally and besides the weight I have another so-called "frame breaker" 7500 lbs airbags
center of the leaf spring frame mounted ,, it is just that when you work with steel as much as I do you kinda get a feel for how strong it is and what actual loads are spread around the frame ,, that Dodge had a design or build issue IMO

 

[dustinrowling]

No, he had way to much weight hanging to far beyond the rear axle. He beat it on rough roads and that was the result.
It isn't just a Dodge thing either.
I don't think frames on trucks are weaker than they were in the past either. The internet and cameras are just making it easier to see. TCs have become heavier over the years and people have loaded and rigged trailers in dumber ways that exploit weaknesses that weren't tested for by lab coats and computers.

If you do a search you will find fords, Nissans, Toyotas, even motorcycles that have broken their frames. Usually doing something they shouldn’t have been doing.

 

[ZMANN]

I still say think that Ram with it's thin tube frame was not built with any overengineering in mind
the Ford looks like it may have broken right where they added the camper tie downs
it would be interesting to see how those were attached and the fail point , tounge weight of the camper
I have a few hitch extensions and even though mine are double 2.5 truss I would never tow a substantial load on a 4 foot extension

 

[Alaskanfun]

I wonder where they’ve been getting the steel for these frames. If it’s chinesium then we have probably figured out the issue.

 

[dustinrowling]

Alaskan,
The problem with the Fords and that Dodge Cummins is not Chinesium steel. The problem is idiots hanging a lot of weight WAY too far behind the hitch. It magnified the weight through leverage and broke the frame. Think of a see saw... you can put the fat kid 3' from the pivot point and the skinny kid 8' out and the fat kid will never touch the ground. You have 1,500lbs tongue weight right on the receiver, no problem, you put 1,500lbs 4ft behind the receiver, that OVER 7,200lbs of tongue weight on the receiver...that's insane....leverage Canberra awesome or awful...the guy with broken frames Failed physics...

Yeah I figured that I was just wondering where they are getting the steel from. You never know, those bean counters can be a real pain. But leverage can be a bigger pain if you’re not paying attention. I said on another post that it looks like loading a small forklift behind the wheels and expecting it to ride there without any issues.

 

[GregWork]

It is also that the leverage is negative. The bed is designed to have a downward force instead of the upward force mid frame caused by the too aft CG
