Ok so I have a 2014 F150 EB SCREW

9600 max tow
1520 payload

New trailer is
8400
Pin on hitch is 1347

I am replacing stock tires with 10 Ply tires

Installing 2" front spacer
2.5" 5000# Air Lift Rear Suspension bags

How much do you gain with the Airlift and 10 ply tires or do you gain at all?

I will be loaded under the 9600 max weight of my truck and won't load much in the 5th wheel up front to keep payload down?

With a payload of 1520 that only allows you an additional 173lbs of weight in the truck. So one person and your hitch would put you over weight. No other cargo or added accessories. The cargo capacity is based on the whole capacity of the truck, not just what the springs will hold.

Nothing, you cannot increase your payload capacity. The tires and bags will only make it handle the load better.

9600 max tow is a trailer that grosses not more than 9,600 pounds. But that's not your limiter. Your limiter is the GVWR of the F-150 which results in 1520 payload.


My F-150 is overloaded over the GVWR and 1,566 payload capacity by my itty bitty TT that grosses 4,870 when wet and loaded for a trip.


You will be way, way overloaded. My F-150 with more payload than yours is overloaded with only 650 pounds of hitch weight.

None of that will increase GVWR or payload capacity. The air bags will mask the sympoms of being overloaded, but you'' still be overloaded.


Forget about a 5er. You cannot even tow a TT that weighs anywhere near 8,400 pounds.

If you don't want to be overloaded when on the road, then buy a much lighter TT or trade for a lot more truck.

Good thread on the subject here:

https://www.f150forum.com/f38/5th-wh...m-doing-52823/

If you are going to do it anyway, add Bilstein HD shocks, E-rated tires and possibly SuperSprings instead of air bags as some air bags conflict with 5th wheel hitch hardware.

I did it for 3 seasons, but with Max Tow and 1850 payload. I made the changes I recommended above. Nothing changes the door jamb sticker, but you would be making most the the changes Ford uses for the HD Payload package.
Although I never felt close to the edge, I traded for an F350 for much more leeway.

Hey Wicked.... We tow a 5er with our little 150 but it's an HD (8200#). Weighed off the lot with me (220#) & 36 gals of gas 6200#'s (give or take, sand & gravel co. scale). Yellow sticker says 2172 lbs of payload capacity and loaded to travel weight is 6580 (added wife, yorkie dog & hitch. Loaded pin weight of 5er is 1360. We're well within the trucks limits and it tow the 5er with ease. Might add the truck is pure stock with exception of spray in bed liner & tonneau cover, no add on extra suspension parts.
We did lots or figuring & research before we bought our 5er. Had the truck already pulling a 31' TT. Pulls the 5er much, much, much better than the TT. Oh yeah we tow in the southern rockies the majority of the time at elevations of 7 to 10,000 ft.

Smokey, you still have that cap on your truck right? That alone is worth almost 2,000lb of trailer at 13% tongue weight and it really does invalidate comparisons of your situation to what most people are up against. Your points are still valid without adding the comparisons to your specific setup. If you didn't have that cap, you'd be overloaded the same amount at closer to 900lb hitch weight instead of 650lb and that would be a more typical setup.

OP, Smokey is right, you need either less trailer or more truck.

My lightweight camper shell weighs around 200 pounds.


But when towing a 5er, the shell stays in the barn. Here's my CAT scale ticket when towing my 5er with that same F-150 without the camper shell or bed rug:


Front axle: 3300 compared to 3650 fGARW. No problem.
Rear axle" 4680 compared to 3800 rGARW. For the math challenged, that's over 1,000 pounds overloaded over the rGAWR of the tow vehicle. Not a good.
---------------
GVW on the two truck axles 7,980 compared to 7,100 GVWR
Oops! That 25" 5er is too heavy for my F-150.
Trailer axles 6,800 = about right for a 5er with GAWR of 7,900. (16% pin weight).
So the trailer was not overloaded, but the tow vehicle was.
----------------
Gross trailer weight close to the 7,900 GVWR of the trailer, or less than the 8,400 pounds tow rating of my truck. So no problem dragging that trailer trough the Texas Hill Country. As with most F-150s, payload capacity is my limiter, not towing capacity.
==============


5ers with less weight than my 25' jobbie are rare. That's why I continue to say you cannot tow a 5er with most F-150s without being overloaded.


I don't plan to tow that 5er with my F-150 again because it overloads my F-150 over the rGAWR and GVWR too much.

Too much trailer, not enough truck. Choose which one to replace. RV sellers love to convince people it will work. It won't.

If anything, I always get more than enough truck to pull a trailer. I do not want to be anywhere near close to the limit. Did it once, won't do it again.

And run that trailer across a scale. Published trailer weights are notoriously understated and of course, do not include ANY gear, water, or anything else. No one tows a trailer completely empty except on the day they buy it. Unless you accurately weighed it, I bet that pin weight is low too.
