I have a 34 ft toy hauler and hardly know its there, but we want to move up to a fifth wheel with slides and travel some.The truck weight is 6,300 lb. tanks full, riders, and receiver. I think GCWR is 18,500, GVWR is 9,200. What would be the max trailer weight I could pull with this truck, and pin weight. THANK YOU!

Had this when I had a 5th wheel. My pin weight was 5k pounds. My RV was 19000 lb. The problem is not pulling, but stoping. On your first trip weigh the rV and truck at a truck weight station and see what you really have.

CCC = cargo Carrying Capacity , and its not can it tow it, but will it stop it it something goes wrong with your trailer breaks, we travel to both sides of the Rocky Mnt. and we are either going up a hill or going down one, we went the path of the MDT's a Freightliner FL-60 4 door sport chassis, this truck is not for everyone, but it was the right step for us

Using your numbers using GCVW you may be able to haul a trailer around 12000 lbs if you include about 200 lb for 5 wheel.

If you use 20% for pin weight that will give you 2400 lb + 200 for hitch from the 6084 RGAWR your truck can weigh 3484 (rear axle) loaded on the scale. I am assuming the 6084 is not a scaled weight. Get a rear axle weight and if it is less than 3484 the rear axle is OK. Note: 5 wheel pin weight can be as high as 25% of the trailer weight. To get a max pin weight subtract the actual weight (+200 for hitch) from the RGAWR (on the door) and you will be close.

Using the GVWR (9200) your weight loaded is 6300 + 2400 +200 (hitch) for a total of 8900.

Based on that it appears you are OK for a trailer with a GVWR of 12,000 lbs. Before purchasing the new RV I would check to see what the truck loaded rear axle weight is.

Hope this helps. Actual numbers for axle weights would be great.

Need the weight of just the front axle on the scale and just the back axle on the scale, ready to roll. The back axle is the more important but might as well get both.

Yes, your GCWR is 18,500. 18,500 minus 6,300 truck weight = 12,200 pounds maximum wet and loaded trailer weight without exceeding the GCWR. However, you probably didn't have the 5er hitch installed in your pickup when you weighed it, so make that 12,000 pounds max trailer weight.

9200 GVWR minus 6,500 wet and loaded truck weight (including 5er hitch) = 2,700 pounds maximum payload available for hitch weight. 5ers with around 2,700 pounds pin weight vary from about 17% to 20% hitch weight. Assume 20% if you want to be less likely to exceed the GVWR of the F-350 SRW. 2,700 divided by 0.20 (20%) = 13,500 without exceeding the GVWR of the tow vehicle.

The lessor of 12,000 and 13,500 is maximum weight of any 5er you want to consider towing with your F-350. GCWR is your limiter.

The GCWR limiter tells you the maximum combined weight of trailer and tow vehicle you can have without overheating anything in the drivetrain and without being the slowpoke holding up traffic on hills and mountain passes. It's a tiny bit misleading for your truck because Ford didn't including enough tranny cooling capacity in the F-350s until 2002 model year.

However, to actually tow a 5er with GVWR of 12,000 pounds without problems assumes you have a huge aftermarket tranny cooler and a good tranny temp gauge to monitor your tranny temps. 225 is the red line for tranny temps for your E4OD automagic tranny, and you never want to exceed that limit - else you'll be replacing the tranny and torque converter. Normal tranny temps should be around 190 or a bit less, rising to over 200 when in town or when towing at less than about 45 MPH.

It's a rare tow vehicle that has GCWR as the limiter as to how much trailer you can tow, but you have one. So don't look at any 5er with GVWR more than 12,000 pounds and you (and your family) should be golden. Pin weight is not a problem if you don't exceed the GCWR of the truck. But assuming your truck weighs only 6,500 pounds when wet and loaded including 5er hitch and a full tank of gas, then any trailer weight over 13,500 will overload your truck's suspension.

However, that 6,500 number is very suspicious for a wet and loaded F-350 SRW CrewCab longbed with 5er hitch, full tank of gas, tools and other stuff in the truck. My SuperDuty CrewCab 4x2 diesel weighed almost 8,000 pounds when wet and loaded for towing. The diesel is about 900 pounds heavier than your 460 CID gasser, and my SD weighed a bit more than your HD, but that means around 7,000 for your truck if you haul as many tools and extra fluids and stuff as I did with just me and Darling Wife in the cab. So don't lie to yourself. Be certain you are using realistic weights.

Ford warns you that you should NEVER exceed either the GVWR or GCWR of your truck. I agree with Ford.

6300lbs is surprisingly low for that truck. My '95 F350 CC LB 4X4 Powerstroke weighed 7500 lb with just my dog and I in the truck. I don't think the extra weight of the engine made that much difference, especially considering your truck was loaded and ready to travel.

Towing heavy and performance turners spell trouble.

For the OP's big-block gas engine, you may be right. But not for a diesel.

I have over 100,000 miles of towing an 8,000-pound 5er, plus another almost 100,000 miles unloaded cruising, with my '99.5 PowerStroke diesel (PSD). Most of it's life my PSD had a cold air intake, performance exhaust system, and DP-Tuner 80-tow tune. Along with full gauges, so it was never ran over the 1,250 pre-turbo EGT redline, 25 PSI turbo boost redline, or 225 tranny temp. With 197,000 miles on it, I sold it to a friend, and he has put another 50,000 miles on it since then. Still runs like a new one.

So towing heavy with a good tow tune did not cause any trouble for me. Of course you have to use your head for something besides a hat rack, drive by the gauges, and religiously change the oil and other lubricants per the manufacturer's guidelines.

Or maybe you don't consider an 8,000-pound 5er to be "towing heavy". My F-250 was almost always slightly overloaded over the GVWR of the truck, so I'd call that towing heavy. But not nearly as heavy as the 12,000-pound 5er the OP could tow without overloading his F-350.

Lots of people put tuners on diesels. Those towing heavy end up building tranny. I tried a tow tune on my 05 and limped my tranny. Removed it. Called Edge and they said to run stock towing in excess of 10,000#.
