Payload Numbers and 5th Wheels.

When buying a 5er payload is the number you have to worry about the most, but you need to check all the numbers. I keep seeing people saying if it was up to the weight police everyone would be towing popups with DRW 1 ton but on the other hand if up to the 1/2 people they could 20,000 lbs 5er with their 1/2 ton just add air bags.

This is not rocket science and its just simple 5th grade math. It just comes down to a numbers game and if you believe that staying within the manufacture GVWR specs and keeping you and your family safe or not.

The numbers below came from Tow Planner - Towing Calculator based on Truck's Payload/CCC - Towing Planner


Most trucks run out of payload long before they run out towing capacity. Tow Capacity Ratings reflects TT weights which have lower payload requirements. The numbers below are from tow planner with only a 175 pound driver and 250 pound hitch and nothing else in the truck (total of 425lbs). If you added a passengers, wood, cooler and etc you must also subtract those weights. Remember not to use the dry weight but ready to camp weight when figuring the weight of you 5er.

Payload of 1500 lbs
You're adding approximately 425 lbs. to the truck. You have 1,075 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 4,300 - 5,375 lbs.

Payload of 2000lbs
You're adding approximately 425 lbs. to the truck. You have 1,575 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 6,300 - 7,875 lbs.

**** Most 1/2 Tons fall around 2000 or less

Payload of 2500lbs
You're adding approximately 425 lbs. to the truck. You have 2,075 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 8,300 - 10,375 lbs.

**** Most 3/4 Ton Diesels and 1/2 ton HD Payloads around 2500 or less

Payload of 3000lbs
You're adding approximately 425 lbs. to the truck. You have 2,575 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 10,300 - 12,875 lbs.

**** 3/4 Gas around 3000 lbs

Payload of 3500lbs
You're adding approximately 425 lbs. to the truck. You have 3,075 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 12,300 - 15,375 lbs.

****Most 1 ton SRW Diesels around 3500 lbs

Payload of 4000lbs
You're adding approximately 425 lbs. to the truck. You have 3,575 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 14,300 - 17,875 lbs.

*** Most 1 ton Gas around 4000 lbs but now you run in to max tow limits.

Payload of 4500lbs
You're adding approximately 425 lbs. to the truck. You have 4,075 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 16,300 - 20,375 lbs.

**** 4500 lbs Start of DRW 1 ton trucks over 4500 lbs.

Payload of 5000lbs
You're adding approximately 425 lbs. to the truck. You have 4,575 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 18,300 - 22,875 lbs.

Payload of 6000 lbs
You're adding approximately 425 lbs. to the truck. You have 5,575 lbs. of payload capacity. Fifth wheels typically have 20% - 25% pin weight which gives you a maximum loaded camper weight of 22,300 - 27,875 lbs.

You convinced me 2 months ago! Thanks for the info.

I still think truck towing ratings should come with THIS clause first:
For Fifth Wheel applications, listed tow capacity ratings are applicable ONLY after the payload requirements are met, considering Fifth Wheel pin weight, occupants, fuel, cargo, and hitch weight.

I went crazy trying to figure out axle ratings, etc......to determine if my then-current 3/4 ton would pull a 16K 5'er.....only to FINALLY realize none of the numbers mattered because I would be grossly over on payload. That is when I realized that satisfying payload first almost always results in the other rating numbers coming out ok.........and vice versa.

And I realize that this gets incendiary quickly......I was initially very upset that my $53,000 3/4 ton wasn't going to work!!! But hey.........as the Cree Light ad says, "If you argue with math, you will lose"..........

Great post! I have tried to explain this many times in responding to posts about weight, but get slapped down constantly as if this is black magic to be ignored.

The importance of this simple math usually comes into play when Joe RV complains that his/her 3/4 ton truck with the super-duper platinum package off-road diesel 4x4 has no payload. EVERY thing you put on your truck, from a decal to a 20,000 lumen krypton light bar will reduce the payload.

Thanks CSwine

Reading one of your posts caused me to start looking , and finally trading in 2012 2500 Duramax for 2015 SRW3500 Duramaxx! Totally satisfied. Took care of the chucking also!

One more tidbit.

Do not go by published/posted weights. Weigh everything on a scale.

My F-150 is in this payload category which is why I have a TT. I did that quick calc before buying our current camper. I need to be able to carry 5 adult sized passengers in the pickup. I don't think there are any 5ers out there with a GVWR in the 4500-5000# range and if there are they wouldn't be large enough to be comfortable for us.

Weighing Sequence/Procedure

Can someone tell me what the proper procedure is for weighing TV and 5th wheel. Seen many procedures on the forum but still confused. Based on what I've read here today I am sure my 1 ton F350 with 3200 pounds of payload will be fine but would like to weigh it all to be totally convinced. Thank you all for the great info you provide. My RV decals say my rv weighs 8196 dry and shouldn't weigh more than 9200 when loaded. Based on Max weight at 20% should be about 1840#. FR factory says it is 1300 dry. Anyway I want to weigh it the correct way when I do it. Thank you all for great input on these issues. I have solved numerous issues using this forum.

You need two weights.

1. The TV ready to camp with everyone in the truck and all the stuff you normally carry in the truck without the 5er hooked up.

2. The weight of the TV and 5er ready to go camping.

Then go here and plug those numbers in - Actual Weights - Fifth Wheel Weights from CAT Scales - Towing Planner

Payload TT vs 5r

Great Post by CWSWine! After looking at several door posts in F250 and 2500 I have come to the conclusion not many people know what they are looking at on the door post (payload), same goes for the door sticker (max vehicle weight). A F150 with HT (11,200) and HP (2,393) had more payload than some F250 and 2500 quad cabs (1,700 - 2,000) but trailer tow was more (?). Usually the max vehicle weight minus the (CAT scale + hitch) = payload (can vary with after market accessories).
