Possible new camper

Hey guys.. looking for something e feedback on a fifth wheel I am looking at and tow ratings on my pickup.

First things first... my tow rig is an 05 Dodge 2500. Quad cab / long bed 4x4, cummins/auto. I do have the 3.73 rear end. I believe the GVWR is 9000, GVWR is 20,000 I have scaled it fully loaded at 7200lbs.

The camper I am looking at is a keystone outback 320FBD. It is called a 32' fifthwheel. Dry weight is 10008 lbs, payload capacity is 1985 lbs. Let's call it full loaded at 20k. (T h at has to be safe right? Max weight?)

If I assume pin weight of 15% max trailer weight I get 1800... with the scale weight of 7200 puts me right at 9000....

Is my math and assumptions reasonably correct?

Anyone out there pulling a similar rig that can comment on how it is going down the road?

I had an 03 Cummins that would pull anything with no issues and I had that truck for 10 years. For sure the air bags on rear springs helped to level the load the few times I had any swaying issues.

Possible typo of 'fully loaded 20k'? Meant 12k? I would think the pin weight could be as high 2400 with a gross weight of 12000, but probably not.
What is the rear axle weight rating? If the truck weighs 7200, + 1800 pin weight = 9000 gross/total truck weight. All of that 1800 is going to be on the rear axle, so you are going to be over on that.
Right at max for gross vehicle weght, over on rear axle weight--not too good. And you are going to be close on the combined gross of 20000.

I think normal pin weight is 20% of GVW or 2400 lbs. Also the OP should be using the
GVWR of the trailer. Forget about Dry Weight.

Rskean... wouldn't the trailers GVWR be its dry weight + it's available payload (for argument sake) when I Don't know the actual GVWR?

Wing nut... Thank you. .. that should say 12k!

Yep, dry + carrying weight = gross. But, also, fivers generally run closer to 20% of the gross than 15% on pin weight. Figure 1800 as minimum pin weight.

I towed a 12000k 5th wheel with a 98 GM 6.5 L diesel for 9 years without any issues. The pin weight was more then 2500 lbs. It felt just right towing it with the 2500 GM.
GM rated the diesel equipped trucks at 8500 lbs trailer. But the 8 LT gas was rated at 12000 lbs trailer.
I am sure the Ram is much more capable.

Yes. That could be said. So that I understand everything you are saying I tried to fine your unit on the Internet. Couldn't find it. Could you post a link? I found the Shipping weight and carrying capacity, but not for your unit. Shipping weights typically do not include any options. Options might include AC, microwave, etc. Then you have to figure in water weight. 155 gallons water is possible between fresh, black and gray. That amounts to 1240 lbs in water alone. But your payload capacity is only 1985 lbs. Then you have food, clothing, camp stuff, etc. With the info provided it would appear that you could easily exceed the GVWR. The GVWR would be posted on a nameplate on the front left side of the trailer. If you are not at the trailer in question, have the Salesman, or whoever take a picture of the GVWR and email or txt it to you. You need all of the information.

Ok yall... need your advice again... wife is pretty seriously looking at a fifth wheel again... this time a Heartland Sundance XLT 298BHS. GVWR on the sticker is 10,500 lbs.

Same truck as before, '05 2500 Dodge with the Cummins. GCWR is 20,000
GVWR is 9000
RAWR is 6,040
FAWR is 5,200

Cat scale on truck:
Front axle: 4,700
Rear axle: 2,960
Total truck: 7,660

By my calculations, this trailer would put me at (using 20% pin wt):
GCW: 18,160
GVW: 9,760
RAW: 5,060

Clearly over on GVW... call it 1,000 lbs over once u add the weight of the 5er hitch. However, I have wiggle room on GCWR and rear axle has plenty of capacity yet...

What do yall think?... this truck should pull a 10,500 lb 5er fine and by the numbers I suspect it will handle the unit well also...

Anyone running a similar truck with this size 5er? Are you using timbrens or air bags on the real axle?

I have an 06 and I would try it. You estimated at the top of estimated pin weight. A scale will tell all. Shift stuff in trailer to balance if necessary.

Heartland Sundance XLT 298BHS

Dry weight = 8810
Dry hitch weight = 1750
1750 divided by 8810 = 19.86%

So yeah, you should assume 20% pin weight. GVWR = 9,900 (not the 9,000 you posted), which is only 1090 pounds more than dry weight. So assume at least 9,500 pounds gross trailer weight, which is pin weight of about 1900 pounds.

The GCWR is not important. That tells you only the weight you can PULL without being the slowpoke holding up traffic, and without overheating anything in the drivetrain of the tow vehicle. The limiter for you is the GVWR, i.e., the weight you can HAUL on the 4 truck tires without overloading anything in the suspension.

So if you get that RV to tow with that pickup, then load the camper as light as you can, travel with empty holding tanks, with only enough fresh water to flush the pottie while on the road, haul minimum tools and campfire wood in the truck.

Sure sounds like a good setup to me. That Sundance is a really nice unit, we looked at it when we bought our Gateway.

Ugh.. I love my wife...

Now she is talking to the salesman about a beautiful 5er... excepts is pushing 14k... That seems like an awful stretch for a 2500 no? I figure I will still be under the rear axle max with the pin weight (5800 lbs vs RAWR of 6040) but GVWR and GCWR will be over.

Got to convince her there is a limit and not what the salesman says.
