So as it states I'm a dumbass. I need a better understanding on how much my truck can actually tow. I don't beileve it's 9k payload.

I have a 2014 amFord F 150 Supercab 4x4 5.0 3.73 gears. Looking at getting a RV. Need to know (and please dumb it down for me please, again dumbass here) how big/weight of a RV I can actually safely tow.

Thank you.

 

show us a picture of the yellow payload sticker on the driver side door jamb

 

I will in the morning. I should have taken a Pic when I was out there earlier.

 

The payload determines what you can tow. Payload is basically the tongue weight of the trailer plus the weight of the hitch plus the weight of cargo and people that will be riding in the truck.

Tongue weight will be around 13% of the total weight of the loaded trailer. Keep in mind that the tongue weight and trailer weights you see advertised are with NOTHING in the trailer. For example, My trailer weighs 5000# empty but weighs 6500# fully loaded with gear, food and water.

 

You will get towing numbers from a brochure. That says how heavy of a flatbed steel 4 wheel wagon your truck can pull. Most of us don't pull flatbed 4 wheeled wagons so the towing numbers are kinda marketing trickery, imagine that. Then you have payload. That is what weight you can place on your truck. Trucks start out with the ability for xyz amount of weight they can handle being placed in and on them. After everything is built and all the accessories are added, you have X amount left you can put on the truck. That is called carry capacity, also know as payload. Typically a travel trailer has a tongue weight of 12-15%of the trailer. So, a 7000# travel trailer, roughly will have 1000# tongue. Add a hitch and stuff in your truck, people in your truck, beer, dog, and everything else, that is your payload. You must stay under what the truck says it can do. Then you add in that travel trailers have a large boxy front, and long sides. The wind loves that and pushes them around. The longer the box, the more the wind catches and pushes. Some say they are okay with this feeling, some dislike it very much. Let us know what your yellow sticker in your door says, we can give a better idea. Most will agree, that the F150s generally play best at a max weight of 7000# and max length of 26' box, under 29' overall length, but again, it depends on how they where built and equipped. In general, your specs you have given imply it will do better than many.

 

Im guessing your payload will not be all that great because its a 2014 5.0, unless you have a rare truck with the heavy duty payload package

 

Based on your listed info and the 2014 Ford Towing Guide,
wheelbase 163” 9200#
wheelbase 143” 9400#
15,100# is your GCWR in either case.

 

if you're getting into RVs you should know the terminology.
The type of RV you want is a "towable"... bumper tow/pull to be precise.
Unfortunately no RV dealer is going to know the exact weight of a unit... only whats published in the sales brochure and that is complete incorrect or inaccurate.
You will likely need some kind of leaf spring support/reinforcement (RAS or similar) and better shocks on the rear at the very minimum to tow drama free & level.
I would start out knowing the exact weight of my vehicle first...

 

Whatever camper you're looking at you should ignore the dry weight and focus on the GVWR. It might require adding the dry weight with the load carrying capacity but that's the number you need to match to the max your truck can pull. Figure about 13% of the GVWR will be your tongue weight which is subtracted from whatever your payload is.

 

Lets add that you need to project the weight you want to carry in the truck. That's People, dogs, luggage, etc. Deduct that amount from the yellow payload sticker and see what you have left for weight from the trailer to add to the truck.
