I'll look at the door jamb sticker (and take a picture) after work tonight and I'll also get the owners manual out (again but I think Frank knows my truck better than me, but his post kinda jarred my memory. I believe I was about 21,000 and I KNOW I was not overloaded an any of the axles , I was concerned about my tires because I didn't buy them with the intent of actually pulling my trailer. I also had a full fuel tank , my wife and dog ,and everything to survive nearly a month "RVing" ,not a lot of fresh water because we weren't boondocking other than the few nights on the road to Quartzsite via Bakersfield and Indio. The scales were within 15 miles of the fuel stop . So I was "pushing it" but with the extra suspension upgrades and exhaust brake I believe I was safe and the truck was plenty capable. That being said I would like a dually for the additional stability and capacity ,however I am nowhere near retirement age or full-timing it so my truck is more parking lot friendly and more suitable for everyday driving use . That was the point to my first post.

OK....I've got a headache from all these numbers!

So....I'm going from a motorhome to a 5th wheel. My F150 just won't cut it, so I'm going to get a bigger truck. I'm looking at:
2014 Ram 3500 Laramie Longhorn package, Crew cab, 4x4, long box, 6.7 Cummins Turbo Diesel, Auto 68RFE 6 speed, LT235/80R17E tires
Website GVWR = 14,000 "Curb Wt." = 6,867
One has a 3.42 Rear Axel another has stock 3.73 Rear Axel
If we get this truck...
What trailer weights do I need to be under?
What #s do I need to be under when I see a unit at the show?



We do not have a trailer picked out yet, but we're going to opening night at RV/Boat show tonight. From web info an example would be:
Forest River Cedar Creek 38CK
GVWR =16,235, Hitch weight...figure 20% of GVWR not what's in lit.?= 3,247

So truck GVWR 14,000
minus curb weight 6,867
equals 7,133 payload for trailer hitch weight and weight of the 5th wheel hitch itself...?
And trailer hitch weight (20% of GVWR) must be under the payload wt. (7,133 in this example)...???

My brain hurts! lol

Does your website show either GCWR or "maximum trailer tow rating" for the 2 trucks. The 3.73 axle ratio truck should be higher on both of these values than the 3.42 axle ratio truck. All else being equal, GCWR and the "maximum trailer tow rating" increase as the axle ratio goes lower (higher numerically).

Either 3500 DRW truck you mention above would almost certainly tow the 16,235 lb GVWR 5th wheel with no problem, but I'd prefer at least the 3.73 axle ratio if it were mine.

SuperSteer,
I just know that the 2500 2001 to around 2007 duramaxs had a GVWR of 9200# and the 3500 dually,s had a GVWR of 11,400#. My dually with my 16,300# GVWR 5er is right at 11,400# and the trailer is right at 16,300# and my rear axle is over 6600# amd the GCWR is right at 24,500#. Your trailer is only about 2000# lighter than mine, unless you are way under the GVWR of the trailer. I was not doubting your word, just doing the math that I know to be true.
Frank

Website GVWR = 14,000
GVWR for a dually is 14,000 pounds. But GVWR for the SRW is 11,500.

Estimate the wet and loaded SRW truck will gross at least 8,000 pounds, and probably 8,500 pounds before you tie onto a 5er. 11,500 minus 8,500 = 3,000 max pin weight. If you can keep the weight of the truck down to 8,500, then look at any trailer with GVWR under 15,000 pounds. That Forest River Cedar Creek 38CK with GVWR =16,235 is fine for a dually, but it's a little too heavy for an SRW.

I suspect you're thinking about an SRW truck, and if so then it doesn't have 14k GVWR. So throw all those numbers out the window. But if a dually is what you had planned on buying, then that Cedar Creek 5er would be fine.

Finally remembered to look at the door sticker and brought the owners manual to work. Frank definitely knows his numbers. ..but I was definitely under all listed ratings, not by much , but It worked great...
