Payload vs. Kingpin Tongue weight confusion

Im getting confused on tow ratings and such. I'm looking at a Ram 2500 Diesel Megacab 4x4 to tow my Jayco Eagle HT 26.5 BHS 5th Wheel (Dont have it yet but it's what I dream of in my sleep).

The truck is rated at a payload of 1920 lbs

The Trailer shows to weigh 7280 lbs dry

The Trailer shows to have a 1400lb hitch weight

According to those specs Im understanding it as though the truck that is rated to pull 15,000 lbs, is almost maxed out on the payload???? That doesn't make sense to me being as though the trailer is only 7,000 lbs???? Dry of course.....

Or maybe I'm missing something and Kingpin weight doesn't calculate into payload like I'm thinking it does. Thanks in advance!!

You're right as to payload and kingpin weight are one in the same. The pin has weight on it and that weight is 100% transfer to the vehicle on hook up. Now factor in family, cargo, hitch, full fuel, plus the added pin weight from a loaded camper and yes you are probably 1K in the red.

I agree that the manufacturers post some numbers that are hard to calculate in real life situations. Best thing to do is weigh your truck with everthing as you would be heading out and subtract that from GVWR on the door jam sticker for cargo capacity.

Now can that truck handle that trailer, yes. Honestly it's about as light as you can go in a 5'er. Where you might have to look into hard is the best hitch setup since that bed is only 5.5ft with the Mega. I would say a sidewinder, but you need to check the clearence between hitch point and tailgate first.

It does , along with you, your passengers and anything else you are carrying that is not part of the truck.

Also any options that you have added count against the factory payload - side-steps, tonneau covers, back racks, caps

Payload is ANYTHING you put In your truck, people, pets, 5th wheel hitch, supplies, tools , etc..AND pin weight of the 5er... I would also HIGHLY recommend to use 5ers GVW to more correctly figure how much you'll be towing and a better idea of REAL world pin weight.. No one tows a 5er "empty" or "dry", it's not a realistic weight when loaded to go camping... I would also figure 20% of the units GVWR to get a more realistic pin weight number...

You can weigh your truck, as stated above, and subtract that number from your trucks GVWR... That's the way "I" do it...but those that are over their GVWR will fall back to their RAWR,(rear axle weight rating)... (Just an example here), if your trucks drive axle weight, completely loaded with everything, but not hooked to 5er shows 3,000# on CAT scales, and your rear axle is rated at 6,000#, it means you "could" go to as high as 3,000# pin weight and be legal, ( if tires cover your axle weight, which they should) (axle weight ratings can be found on placard on drivers side door or door jamb).

A mega- cab is a heavier truck due to weight of the cab.

What is actual GVW of the 5er you want?

ON EDIT: Looks like GVW on the 5er you want is 9950#, possibly having a more realistic pin weight of close to 2,000#, IF fully loaded...After looking at 5er stats, don't see an issue with the 2500 towing it, BUT, If you think, "down the road", you might go to a little heavier 5er, you could look at a 3500 SRW Mega also....not that much difference in pricing between 2500 and 3500 SRW trucks and 3500 will give you a little more payload.

+1 for taking a look at the 3500. Does the 3500 come in mega cab SRW? I only see them in DRW around here.

That Cummins is a heavy beast. My gasser has about 1K lbs more payload because I DON'T have the diesel.

Just food for thought: Do you really need the Mega Cab? It doesn't really give you that much more rear seating room over the crew cab. Most of the extra space in the Mega is behind the rear seat. When it was time for me to make the decision, I sat in both, and decided I didn't need the extra storage. The rear passenger space was more important to me, so I abandoned the Mega Cab as an option.

Thanks everyone for the replies so far.....I think I might re-consider the 3500 over the 2500 for sure. I like the ride of the 2500 with the coil sprung rear end which is really the only reason it was my first choice.

The 3500 might be a little more rough but that's not that big of a deal to me i guess. Would love some input on the 3500 ride quailty.I'll have to take a 2nd look at the crew cab over the mega cab but I think the gain in payload is only 200 lbs.

I'll add my point to the excellent advice already posted.
Your truck's "payload" number is for the front AND rear axles. Each axle will have its own max weight (GAWR) the sum of which may or may not add up to the payload number. IMHO the ONLY way to know is to visit the scales and get the actual axle weights. This will show you how much weight you can add (people, fuel, gear, hitch and finally pin weight).
The CAT Scale is your friend.

Can't you get the 3500 with an air bag setup too? I would think empty they would ride pretty nice.

I have the mega cab 3500 short bed. Just measured the bed. 6' 4'' actual measurement of the bed. Personal accounts of people with this configuration say if you have a 5th wheel with the tight turn type technology that manufacturers are using with the angled front cap, they don't need the slider hitch. I'm sure every TV / 5er configuration is different, so you just don't know what you like till ya try em all...

The ride is ROUGH! No worse than the Ford or GM ton trucks I test drove. The 2500 rides so much nicer. I droped my tire pressure to try and smooth out the unloaded ride.

If I was in your shoes, I probably would consider going with the 2500, then deal with axle weight rating and tire weight rating issue.

Compare payload of the crew cab compared to Mega cab. The payload spec sheet does not have much more payload between crew cab and mega cab 3500's. Unless you want the 8' bed. The long bed has more payload. They seem to just lower the GVWR with the 3500 crew cab.

My 3500 Mega cab 4wd SRW Short bed diesel has a GVWR of 12,300lb (with 4,270 available payload). The 3500 Crew cab 4wd SRW Short bed diesel has a GVWR 11,500 (with 4,160 available payload). But the 3500 4wd SRW diesel with 8' bed has a GVWR of 12,300lb (with 4,480lb payload available).

The 2500 crew cab/mega cab difference is more significant because they all have the 10,000lb GVWR.

Good luck finding a 3500 mega cab with a short bed and SRW. They are much more rare than the DRW or the 2500's. When I purchased mine a few months back, there was only 2 trucks within 600 miles that had this configuration (plus a few other options like color, 5th wheel/gooseneck prep, etc)

The real world difference in the mega cab -v- crew cab is minimal. When I was shopping trucks, I took measured the difference in leg room in the back seat between the 2 configurations. The mega cab had about 1 inch more actual leg room. The extra length is behind the back seat. The mega cab back seats recline a bit, and there is about 5 inches of floor storage behind that seat.

If I had to do it over, I probably would have still got the mega cab, because it did have more payload than the 3500 Crew cab (4wd figuration). If you want 2wd, the crew cab will have a couple hundred more pounds of payload).

For us, the Chevy back seat was just too small for our preference (we have kids), the superduty was a big contender, and has a good back seat, but ultimately ruled it out....

On a side note, be sure about the camper you want before getting the new truck. I picked this truck because we were moving to a 5er bunkhouse where we would have enough truck for any bunk house that is available. Now we are going to a toy hauler (using the garage as a bunk room) which has much more pin weight than the bunk house 5ers. I probably would have got the DRW had I known we would end up with a toy hauler.

Good luck. PS- the ride is ROUGH!
