My 40' Cardinal GVWR is 15,915 however on weighing the 5er Dual axles I was at a loaded weight of 12,544 lbs and after calculating truck axle loads found my loaded Pin weight to be 2749 lbs.

I see that you haven't looked at the New Ram 3500 SRW. The specs for this are higher than the either Chev or Ford.

My trucks Max GCWR is 25,300 lbs. My current loaded GCW is 23890 lbs. I am under the trucks rated GCWR by 1,410 lbs with my set up.
It all comes down to the final numbers and not necessarily the weights of individual components.

Here's a bit of info on the Ram.

So what is your gvw on your truck with the trailer hooked on that is the one that matters with the single rear tires and rims

The stability when towing with a dually is much better compared to towing with a srw. It would be great if people could tow with both and then make a decision. The only time that driving a dually feels different is when you look in the rear view mirror and see the fender, it's no different sitting in the cab looking forward. Go for the one ton truck at least.

Watch out for the GAWR on your rear axle. Try to be certain the rear axle can support the weight of your trailer pin, truck chassis and other truck payload.

Confused about what kind of truck size?

What is the gross weight of the fifth wheel and hitch weight if the camper? Buy a truck that has limits above those numbers. Best combination of motor & transmission on the market is the Duramax & Allison transmission. I had a dually but traded it off. Great for pulling but to drive around is a pain.

Are you asking me or the OP?

If you're asking me, here's my numbers.

GVWR on my truck is 11,700 lbs.
Currently loaded with full fuel, my peeps, pets, gear and hitched to the loaded 5th wheel, I weigh in at 11,346 lbs.
I'm under my trucks Max GVWR by 354 lbs.

My trucks Max GCWR is 25,300 lbs. My current loaded GCW is 23890 lbs. I am under the trucks rated GCWR by 1,410 lbs.

I'm also running Firestone Transforce AT 10 ply LT285/60R20 tires on my truck. Better weight rating than 17's or 18's.

Trust me. I spent about 3 months doing my homework to ensure I had a worry-free set up. I was challenged all the way through the process by those on this site who told me I was crazy for not getting a DRW till I proved all my numbers. I'm glad they did because I probably would be like many others and buy something inadequate.
Based on this 5th wheel, I would have been over if I bought a SRW Chev or Ford.
The Ram 3500 got me covered. It's powerful, strong and stable. I have absolutely no issue with my set up. It's under specs in all categories for both the truck, 5th wheel as well as combined.

Dog, it looks like you did a good job. Just a couple parting questions; is your truck rear GAWR also within tolerance under load? Have you done an all wheel weight on your trailer wheels? Typically the driver side and also the driver rear will carry more of the trailer weight than the other trailer tires. Good on you for getting things within tolerances!

Thanks Pullin' Chocks.
My trucks GAWR (depending on where you look) is 7280 lbs.
My rear axle weight loaded with the 5th wheel is 6364 lbs. so I'm under my trucks Max GAWR by 916 lbs.

I haven't done an individual wheel weigh in. Just truck front and rear axles and the 5th wheel axles.

Sorry to the OP for sidetracking your thread, but as you can see by the questions asked, there are many components to arriving at the right combination of truck and 5th wheel to ensure you have a safe and trouble free experience.

Bottom line with a SRW truck is will the two rear tires support the load?????????

To be clear Dogwatch is not a full timer. If he was I guarantee his rear axle would be overloaded with the RV he has. Believe me when full timing you add WAY more weight than you think.

Another thing to consider is with a SRW especially a short bed towing such a LONG RV the wind can get ahold of you when you least expect it!

You may have a point there! Throw in my wife's shoe collection and I'd be done for! LOL

When I weighed my srw with the trailer I was still within the gvw of the rear axle but my tires and rims were overloaded. My pin weight is 4280lbs.i certainly did not want a dually but common sense dictated. Empty the dually rides smoother mind you I went from a short box to a long box.

Concrete transit mixers and fuel haulers in CA run singles all around. Your dual theory is full of holes. The newer wider singles will carry same load as duals. On singles you have a super single on both front and back axles. My first tow vehicle was a dually. Pain to park in shopping centers. My newer is a single wheel. I still own both. No difference in stability. 79,000 miles of towing with both.

I haven't seen any pickups running super singles yet. I pulled my 5th wheel with a C3500 SRW for 3500 mi, then I bought a DRW and pulled the same rig. I thought it was night and day. There's no way it is not more stable. It's just physics, with the wider stance. I drove the DRW 68K mi in 22 months, as a work truck. I don't recommend driving a DRW for that, but pulling a 18K 5th wheel, yes. 2 MPG less and 2 extra tires to replace.

No wonder your confused.
Fifth wheel street has a poor weights calculator as it calculates numbers from a GCWR which is not on any truck.
It also ignores the trucks GAWR's/tire load ratings and particular the trucks RAWR/tire load ratings as it carries the load.

A 250/2500 truck can have a 10000 GVWR and a 6000-6500 RAWR which leaves payloads in the 3000-3200 lb range.

The 350/3500 SRW trucks can have 10000 up to 12200 GVWR with a 7000-7050 RAWR which leaves payloads up to 4400-4500 lbs range.

The 350/3500 DRW trucks can have 14000 GVWR and up to 9850 RAWR for 6000-7000 lb payload range.

All weight numbers depends on cab and drive line configurations per each truck. I wouldn't mess with a gas engine for trailers this size for traveling the USA.
.................................................. ...........

The Big Country 3070 has a 15500 GVWR and a 11740 lb dry weight which leaves a 3760 lb CCC. I doubt you will load 3700 lb in the trailer so lets say 1500-1800 lbs = around a 13500-14000 lb trailer which means a 2800 lb pin weight plus a 60-100 lb new gen hitch = 2900 lbs. Now add another 300-400 lbs for folks and junk in the truck = 3300 lbs .
Lets round it off at 3500 lbs.

The F350 SRW super cab or crew cab long bed 6.7 diesel with the 11500 GVWR and a 7000 RAWR has 4000-4400 lb payload.

The 3500 SRW Ram 6.7 diesel with a 12300 GVWR and a 7000 RAWR has payloads up to 4500 lbs.

The GM twins 3500 SRW 6.6 diesel and 11600 GVWR and 7050 RAWR has 4400-4500 lb payloads.

Any of the new gen trucks mentioned will have no problems with a 13k-14k lb trailer.
Now if your pulling a trailer with a actual 15500 lbs + weight for 6 months all over the USA then a 350/3500 DRW will also work. Your call on which works for you.

Check out heartlandowners.org forums. There will be folks over there with the info you need.
