HELP, 320RS Owners PLEASE!!!!
I am in a complete and total conundrum here!!! I weighed my rig and the numbers are, well SHOCKING!!!! According to what the CAT scale reported, I should have bent axles, no tires and the springs should be broke in two on both sides.
Truck stats -
2011 Laramie Longhorn, 3500 SRW, GVWR 10,100, FAWR - 5,500, RAWR - 6,200
Towing capacity 13,500 (from the RAM Customer Service) GCVWR - 21,000
Here are the Scale rates (in pounds as Kilo only confuse everyone except us Canucks (and we're bi-weightial (my word and I'm sticking to it)))):
Bare truck - Me, my Wife and a full tank of Diesel
Front - 4940, Rear - 3280 (Total 8220)
Stand-a-lone Trailer - (Washer/Dryer, 5500 Genset, King Bed, Trav 'ler Satellite Dish, 1/3 tank of Fresh Water, a few clothes, tools (a wrench set), two folding lawn chairs, slide covers, 2nd AC and 6 point leveling system)
On the landing struts - 4,420, on the Axles 8,680 - Total 13,100 (I had the struts at the 12th notch and trailer was at disconnect height)
Combined unit, with my wife and I on board the tow vehicle
Front (TV Steer axle) - 4,920 (lost 20lbs to the rear)
Rear ( TV Drive axle) - 10,980 (????????? The Drive axle has gained 7,700lbs)
Trailer axles - 5,440
Total combined 21,340 (yes over GCVWR by 340lbs)
There are no bows between the truck and trailer, everything is pretty much level.
OK, I knew that the factory pin weight would go up, the W/D (@ 250lbs) and gen set (listed at 250lbs) are forward of the axle, and add another what 50 to 75 lbs for the king bed upgrade + the 6 point systems (but most of that should be rear or at the trailer axles, the only weight would be the two motors for the front struts say what, 100lbs), so lets say we've added 675lbs forward of the axles.
The factory pin weight of a bare 320 is listed at 2,015lbs and I think the factory bare weight for a 320 is somewhere around 10,900lbs. That's puts the hitch weight around 18.5% of the trailer weight, which is in the acceptable norms of 15 - 25%.
So, mine came off the factory floor weighing 12,900 with the extras, so based on what we've seen, the hitch weight at 18.5% would be somewhere around 2,386lbs.
I've only added 200lbs with the water, clothes, propane, battery, chairs and satellite receivers to bring the trailer weight up to 13,100lbs.
If I do the prescribed math for calculating pin rates of a unit using the 15-25% method, a 13,100lb trailer should only have a pin weight of between 1965 and 3,250lbs and the truck back end weight of 3,280lbs should put me at 6,530lbs.
Where the HE** (ah) CK is the extra 4,400lbs coming from? How does 675lbs rotate that much weight forward to the Pin???
According to these scale figures, there isn't a 1 ton SRW or Dually out there that can pull this puppy. The new 2013 Dodge 1 Ton DRW is suppose to pull 30,000lbs, but the RAWR of the new truck is only 9750lbs. According to my scale figures, my trailer is 1,230lbs over the RAWR of the new truck.
Now to add insult to injury, I just looked at a new 2013 Ford F450 King Rancher Dually. The RAWR on that machine was only 9,100lbs. Sorry "Ford is the way to go" guys, but open your driver door and have a look at the restrictions.
Neither Ram or GM make a 4500/5500 that has a cargo box on the back, they're strickly Chassis models and to custom it into a TV hauler or put a custom box on it, an extra 10 - 50,000 dollars...
On top of this I went to a Spring and Airbag shop, I was advised that adding springs or airbags would not distribute enough (or any) weight back to the trailer. So I went to a tire shop to see if I could buy larger or higher rated tires (mine are currently 10ply E-rated tires) only to find out that there are no F or G rated tires available for LT type tires (at least not in the size I require), also that if I increased the size of my tires so that the weight bearing number were high enough to support the reported scale rate, I would have to run OffRoad nubbies.
AHHHHHHHHHHH!!!!!! I'm afraid to hook up and go anywhere now!!!!
HELP, where could I have gone wrong???? I went as far as going back to the scales to see if there was anyway that I could have had one of the trailer axles on the same scale as the drive axle.
Please, I can't afford a mini Freightliner just to pull this "LIGHT" trailer...
