Hi Guys,


So here goes the age old question... Looking at purchasing a 2016 Keystone Fusion Impact 39ft model 361. Pin weight of 3,115, Dry Weight 12,820, Cargo 4,180.
I have a 2016 F350 6.7L Diesel SRW Short Bed with a GVWR of 11,500lbs. I weighted the truck yesterday and I'm right at 8,500lbs, giving me a pin weight capacity of 3000lbs. This is also without the 280 pound fifth wheel hitch that needs to be installed. which puts me around 380lbs over before loaded. I do have a 900 RZR that will sit in the garage that will/may take some weight off the pin. Also the RV has a 5500 Omen generator in front. Does anyone know if the generator weight is included in the advertised pin weight? I know I'm over already but...... Thanks

 

I've been here for a few years, and I can guarantee that the issue is not too much camper. It's always, not enough truck. The boys here love crazy large and heavy RVs. They are committed to upgrading the truck portion of the equation as needed.

Hahahahaha!!!!!!!!!!! Sounds just like me, when I bought my Raptor!!!!!! Only I had a 6.2 gasser with 3.73 gears!!!!😎😀 Now have the dually and don't worry about how I load the Raptor, or whether or not I have the garage full!!
Have fun!!!! Bring the rig, with RZR to AZ and lets go wheeling!!!😎😎😎😎

 

I'm in the same situation. Looking at a Momentum 388. Hope my SRW is up to the task.

 

You don't say how mu much room you have on the axle weights or the tires.


Those are what it more important than the 3K payload you reference.

 

On the generator question, is it an option or a standard on your RV? If it's a standard, it's included in the pin weight. If it's an option, it's not. Also remember that the manufacturer listed pin weight is "dry" as well. That said, this doesn't mean your pin will go up significantly when loaded. Mine loaded with the garage empty is within 50# of the manufacturer's dry weight. With the garage full, it's under the listed weight. Every RV is different so the old armchair engineering "pin will weight this % of your total" may or may not apply. The only way to know for sure is to weigh it. A Shurline scale will do the trick without going to the CAT scales. The dealer might even have one so you don't have to make the investment.

As to the hitch, 280# seems awful heavy? Most weigh around 150#.

Loading the garage will offset some but not much. With 2k in my garage my pin only gets about 200# lighter. But again, every hauler is different...

Lastly, 8500# is just about where my 2012 was with family in, full fuel, and hitch in. (8550# actually...) So, you'll be a little over that once your hitch is in. I'm not sure if you weighed your rear axle but mine was 3550#. Ford rates your Sterling 10.5 to 7k. So, you're likely just at or right around your rear GAWR. Your only concern at that point would be tire ratings. If you have 20's, you've got 7500# of capacity. 18's give you 7280#. As long as you're under on one of those, I'd be fine with your truck and potential RV.

 

Read GAWR = 7,000
Front GAWR = 6,000
On the scale the Rear axel weighted in at 3,560
Front axel at 4,800 for total of 8,460 without hitch
20" tires rated at 7,500lbs

 

You are fine. Enjoy.

 

Thanks for the response, that makes me feel a little better

You're right on the hitch weight, looked it up again and only 200lbs. It's a B&WSlider
Read GAWR = 7,000
Front GAWR = 6,000
On the scale the Rear axle weighted in at 3,560
Front axle at 4,900 for total of 8,460 without hitch
20" tires rated at 7,500lbs
The truck also had the exhaust brake and I'm adding air bags this weekend. I understand the bags don't add any capacity to my truck and will just level the bed.

As you said only way to know for sure is weigh on a scale. I spoke with the RV dealer yesterday about all this and of course he couldn't tell me I wouldn't be over on the pin as you can't argue with the numbers. He did say I could bring the truck by today and they would throw on the hitch and I could take the RV out for a test drive to see how it handles. I thought sure and will head straight to the Truck Scale and weigh the camper. Since I already have the truck weights all I need to do is put the truck (all four wheels) on the first scale and the camper on the second? This should give me pin weight and camper weight?

 

Thanks Scott....

 

Bob, if you go to a CAT scale there will be enough pads that you can weigh your front and rear truck axles separately. So, front truck axle on one pad, rear truck axle on the next, and trailer axles on the last pad. That will give you the most info. Then you can just combine your front and rear axles for the total truck weight. It will be interesting to see what happens out front. On my last truck, the front actually went down when hooked up with my hitch in the rearward position. I haven't weighed the new truck with the RV yet...

PS: I agree with Scott that you'll likely be under tire and GAWR ratings so good to go... Keep us posted.

 

Hi Rodney,


Great idea, I will weigh with your suggestion and post the results.

 

Another tip when choosing a TT or a 5er or gooseneck is to go off the "Wet" weight or GVW of the trailer. Ignored the dry weight. Dry weight is usually without the battery or propane and bottles plus all your gear and maybe the spare tire too. You will never travel that way. Go off the GVW and factor 20% of that for the hitch weight which becomes the payload over that rear axle. Some may go over the front axle as well. toyhaulers are a little more difficult as loading the rear with toys can take some of the load off the pin.

 

As I said, they are all different Scott. Look at mine. With 2k in the garage and a total RV weight over 20k, my pin is only about 2600#. However, with nothing in the garage sitting at 18k, my pin is still only 2800#. Either way, no where the 20% that so many use to estimate their pin.

 

That is what I was trying to say, toyhaulers are different and harder sometime to get the pin wt.


But using the GVW as a reasonable first look I think is important. It should start the though process of doing some fact finding on what it will actually be upon various loads.
