SD to 5.9 12v towing

[98dango]

Ok hears the deal I currently have a 2000 f250 5.4 that tows ok. My door says 8800 combined. Now figure the truck is 5500-6000 now. If I swap in a 12valve my weight will go up. So in theroy I can tow more but legally I can tow less correct?

I am not looking to be loaded to 13k I want to haul a 10k total weight toy hauler.

So my problem is I love my truck now the color body the fact its been in the same family for 12 years. But do I need to be looking at a f350 or 450

Not very EXPO related but this is my house.

I should also mention I plan a travel trailer and not a 5th wheel. The bed of the truck will be mostly empty 2 gas cans and one heavy but movable by one guy tool box.

It isn't as much of a GVW (gross vehicle weight) thing, as it is a GCVW (gross COMBINED vehicle weight) thing. If you were looking at a slide in truck camper, the 12v would eat up legal weight capacity. If you are looking at a 10,000 trailer and your truck weighs 6000 now, you are at 16,000 GCVW. The 12v would add maybe 500 lbs? It all comes down to your door sticker vs your scale weight. What does Ford rate your towing capacity at?

One of the big factors is brakes, so augment your set up with an exhaust brake and a quality trailer brake (I use a Tekonsha P3) and you'll be comfortable. Airbags and an equalizing hitch would help too. I don't think you need to go to a F350 or F450 for 10,000 lbs, assuming you have 4.10 gears.

Ford specs show 8800 lbs is you GVW, not GCVW. Towing specs show 5.4 auto: 7600 with 3.73 gears, and 9100 with 4.10s. For manual trans: 7700 with 3.73s and 9200 with 4.10s.

From what I can find its 10,500 trailer with 3:73 gears. 8800 on truck and 10.5 trailer for a total of 19.3. If I had factory 4.30 gears it would up me to 10.7. What we are looking at is a 28' toy hauler that is 9800

For comparison a 7.3 equipped truck is around 6900 to 7200 depending on added options bumpers ect.

Dry Hitch Weight 987 lbs. (448 kg)

We want to haul 2 quads 600 lbs each 500 and 550 according to the factory but I like to round up.

My original plan was a flat bed and 2 quads but then I had to do the math

900 lbs hitch weight 1200 lbs in quad and figure add 200 for flat bed. 2300 on the truck so I figure with the 12v extra 500-600 that sets me right exactly on so most likely over gvw before I get to gvcw

Be careful about your calculations. GCWR is not the combined total of GVW and Maximum trailer weight. If you max out the payload on the truck, you won't be able to tow the max as listed.

Also, have your truck weighed. I had the exact same truck as you with the v10, and I seem to recall it was a lot heavier than 5500. I'll see if I can find it.

Edit: 7100lbs

I would just buy a truck that comes factory with the motor in it. Much more reliable and cheaper that way.

I agree with above. Look for a Dually like Rethies! Problem solved.

I know in Washington you could have the GCVW could be changed if the proper upgrades were added. For example if your truck came factory with 3.73 gears and you upgrade to 4.10 gears you could have the GCVW increased from 16,000 to 18,000, (05 SD with 5.4 and Auto). You may check with the proper authorities in your state regarding a motor swap and how it affects your GVW and GCVW.

Ok buying a dually will never happen and by never I mean never ever.

I have the 5.9 6 speed and Ford t case already bolted together. Had this set up in my first superduty bent frame and smashed cab.

I could buy a new truck but I really honestly don't want to. And from what I see a f350 swr is the same as my f250 5.4. So in less I get a 2wd I will not gain any thing.

Now a 5.9 swap puts my truck right at 7k
That leaves me 1800 to add 800 hitch weight in theory correct. I am just having a hard time that I need a f450 to leagly haul a 10k toy hauler. Yes the sales guy was all you'll be fine I just sold one to a guy wit a f150 Eco boost. Fine and leagle are not the same. We all know the truck can do what I want to ask of it. And I don't see a 12v total weight being much different than a 7.3.I just like the 5.9 better. If I had an orignal 7.3 truck no one would think twice. From my research all short bed crew cab 4x4 have the same 8800 combined and 10.3 3:73 or 10.5 4:10-4:30 but the 8800 stays the same.

So do I honestly have to get a f450 or dodge 4500 to tow 10k trailer.

If you feel your combination of parts is up to the task then go for it. Just realize if you knowingly tow more than your rated for and something bad happens your insurance co. could come back on you. I personally wouldn't worry about it if I was confident in my setup.

In CA any trailer over 10k requires either a class A or rv endorsement. As for weight rating it depends on the hitch setup. Most bumper pulls are limited to 1k tongue and 10k trailer with weight distribution. 5 wheels are rated for more that that.

Also look at axle ratings, tire load ratings and what not.

It all gets fuzzy when you are trying to push the limits of the OEM tow rating.

That toy hauler is rated to be safe to that 10k limit. I doubt it actually weighs that. Deosn't the trailers sticker have an actual weight listed on it? Iif the trailer really deos weigh that much unloaded, then you're toast. In Ohio, I can tow up to 10k on my license, real weight, not trailer rated weight.

So get the actual weight of the trailer, toys, water, fuel, gear, and Cummins engine and subtract that from your GCWR. Then also make sure you're not exceeding GVWR (unlikely with an empty bed and only tongue wt and the diesel), and of course, do not forget your front axle rating and your front tire ratings.

Well after a long talk with Ford and the state of Montana my licenseing state it dosent matter what I do I need a new truck. Witch sucks my total weight is only 13,500 so I will be over loaded on my way home or darn close. Now same truck with a 7.3 20,000 Ford says they are identical trucks but as built is as built. I could do things to make mine but never honestly leagle. The state told me that it would never be a problem till I had a problem but any accident would be my fault in court weather it was or not. So I have no choice but buy a new truck.

People assume its how much they weigh, but its not. Its how much the axles on the trailer are rated for. You need a class A just to pull an empty flatbed trailer if it has dual 6k axles. It may only weigh 2500 lbs, but it doesn't matter to the authorities.
