My CAT Scale results, I need your opinions!

I finally made it to a CAT Scale today, I need your help determining if my WDH is set up correctly and if I can safely add a 80# MorRyde 20x90 sliding storage tray.

TV is a 2014 Ford F-150 SuperCab 5.0L 4x4 with a 6.5' bed. GVWR is 7350# Front GAWR is 3750# and Rear GAWR is 4050#. Cargo Carrying Capacity is 1639#. When I weighed, my wife and I were inside along with the normal load that we carry plus a full tank of gas.

TT is a 2017 Jay Flight 21QB, yellow sticker on it weighs 4575#

At the CAT Scales, my weigh was truck as mentioned above with no WDH

Steer Axle 3560#
Drive Axle. 3080
Net weight. 6640#

Second weigh was with TT on the WDH, but bars no applied

Steer Axle. 3200#
Drive Axle. 4280#
Trailer. 4700#
Net weight. 12180#

Third weigh was with TT on the WDH and bars were applied

Steer Axle. 3460#
Drive Axle. 3880#
Trailer. 4840#
Net weight. 12180#

Your thoughts as listed? And you you believe I can add an 80# sliding storage shelf to the pass through?

Please comment!

Frank,

Look in your owners manual to see what Ford recommends for the wdh adjustment. It used to be to return 100% of the lost weight back to the front axle, then they went to 50%, and last I had read they only suggest 25% return.

If its 100%, you could possibly transfer a little more weight to the front axle as mentioned. You are 100lbs less on the front axle hooked up vs the truck only front axle weight.

It appears your weights are:

TT- 5540lbs
TW- 840lbs
TW %- 15.16

Your total truck weight (on the trucks tires) with the tt hooked up and the wd bars installed is 7340lbs. You stated your GVWR is only 7350lbs, so that is only 10lbs left before adding your 80lb drawer to the front pass through. The majority of that weight will be tw, which will only increase your trucks total weight. Chances are you will still be under your rear axle rating with the wd bars installed, but defintiely over on the GVWR. Only you can answer the question on if you want to run over the GVW or not. Personally I wouldn't add it, but that's me.

Now if you could move some things around to lighten the tw a little, then add the 80lb slider, keeping the tw roughly about the same.

As we were chatting about in PM, see if you can find the GCVWR rating, it might be listed at GCWR. It is probably on that dataplate where you got your axle limits and GVWR for the truck. This is the combined max weight for the trailer and truck. As I mentioned you are cutting it close on GVWR and adding the shelf will put you over that number but you are still good on the others like Axle limits. I suspect you are going to be fine on the GCVWR. You are at 12180 as I had mentioned and if I were to guess your truck is probably 13.5K-15.1 on the combined rating depending on your gear ratio. I think I had guessed in the PM that you should have a combined rating of about 14K which was pretty close to the ballpark as this is normally a good guess for a 1/2 ton truck. It is always better to look it up rather than guess.

I mention the combined rating because right now because you are at the GVWR limits but look good on cargo and axle limits. You didn't mention your max hitch rating but I suspect you are fine there as well. If your combined rating was 15.1K and you are only at 12.1K I would say, if it were me, I would be fine pushing the GVWR a few pounds. Lets say you have the 3.55 gear ratio which is probably more common because of the higher MPG numbers, then you would have a 13.5K combined rating which is probably still fine, just closer on the numbers. If you were blowing past several of those limits it would be a very different story. People do it all the time, and it is up to you but that is my comfort zone if it were my truck and trailer.

Here is where I got the numbers on the GCVWR but look at your data plate.

https://www.ford.com/resources/ford/...F150_Sep11.pdf

The other bit of information that you had sent me in PM that you left off of your post here was your measurements.

Vehicle loaded with no trailer or WD hitch.
L/F height is 39 7/8". R/F is 39 7/8"
L/R is 40". R/R is 40 3/8"

Vehicle loaded with trailer no WD Bars.
L/F height is 40 5/8" R/F is 40 1/2"
L/R is 38 1/4" R/R is 38 1/4"

Vehicle loaded with trailer and WD bars.
L/f height is 40 1/8". R/F is 40"
L/R is 38 3/4 and R/R is 39"

Someone mentioned above that you could shift more weight to the front by loading your bars a little more. What kind of WD hitch do you have? If chain based you could go up a link. Right now your front is higher by 1/4" on Left side and 1/8" on the right which is pretty close. Ideally you want to have the front a bit lower than the measurements before hooking up everything. So you could go a bit more. If you add another 80lbs you will want a bit more pressure on those bars.

Of course the other option you have, depending on trailer layout, is to shift some of the heavier cargo to the rear of the camper at least while in transit. For instance if you have any totes or loose things you throw in as you head out you can put them in the back. For us we toss that stuff in the shower or rear bunks. For your camper you could put it under your dinette, on the bench or sofa. Anything you currently that is heavy, maybe a dutch oven or such, should go in that under dinette bench storage if not already there. The max weight of your camper is 6500 so you have quite a bit of cargo capacity left in the camper and you are looking pretty good on your tongue weight number so adding cargo to the rear will not hurt anything at all.

Good Afternoon! I am just logging on to read the message and according to my owner's manual, my F-150 SuperCab 4x4 with a 5.0L and .355 gears has a maximum GCWR of 13,500#, the placard on the door jamb does not list a GCWR, it only lists a GVWR of 7350#. My max hitch weight with a WDH is 1500#.

Two issues come to mind, my truck has a solid folding tonneau cover that likely weighs around 60#, the other issue is that my TT has two full 30 psi propane tanks that are likely 55# each. I can remove the tonneau cover for the camping season and put it back on for the winter months. I can also remove one of the propane tanks, one tank is plenty of propane for our camping season.

Thoughts???

I traveled back to the Jayco dealer to have my Equalizer WDH tweaked. I had planned to have the tech add one washer to the system, but my salesperson recommended adding two. I will fill my TV with gas, then take measurements without the TT, then hook up to the TT and take measurements again. If the measurements look good, I will take the combination to the CAT scale to check steer axle, drive axle and trailer weights to verify if the hitch is adjusted properly. Stay tuned!

Frank,

Are you sure your trucks receiver hitch is rated for 1500lbs tw with a wdh? Is it a factory hitch or aftermarket hitch? I ask because I have yet to see a F150's factory hitch rated for more than about 1200lbs. And for your '14, according to this Ford Towing Guide, your receiver hitch is only rated for 1130lbs. It is listed in the chart in the bottom right of page 3.

As for reducing the tw, what about running 2-20lb tanks vs the 30's? It may be easier to have two tanks on there vs just one. You may need to buy a 1/2" threaded rod for the tank clamp.

Just make sure you don't reduce the tw to much and and end up with sway caused by to light of a tw.

Regarding the wdh adjustment, adding two washers may be more than you need. Especially if you reduce the tw some by swapping/ removing a tank and by removing the tonneau cover.

Let us know how it all works out!!!

Bubba, thanks for pointing the hitch facts and I mistakes what I read. The hitch is rated for 1,050 lbs with a WDH. Now that I see the extreme angle caused by the addition of two washers, I am heading back to the dealer to have one removed. I believe that with running six washers and leaving the two 30# propane tanks as is, I will be applying a bit more weight onto the trailer axles and likely adding some weight to the steer axle. Yes?????

Yes that's exactly what changing the angle of the hitch head does. Adding 1 washer makes quite a big difference. The Equalizer hitch can run a maximum of 8 washers although only 6 are provided at purchase I believe. By adding a washer you will also transfer some of the weight back to the trailer axles which will relieve some of the weight carried by the truck. This will give you a bit more room between your truck's weight and its GVWR. You were 10lbs below before, and I'm guessing now you will be 50ish below. Just a guess.

Okay friends, here we go, I've added one washer and using a total of six washers. My intent was to reduce the tongue weight by transferring some weight back onto the trailer axles, I wanted to reduce the amount of weight that went onto the truck because I wanted to add an 80# sliding storage shelf into the front pass through of our TT. These are my results from today...

TV without trailer and hitch
Steer Axle is 3560 L/F 40 1/8". R/F 40 7/16"
Rear Axle is 3080. L/R 40 13/16". R/R 40 3/4
Net is 6640

TV with trailer and hitch with bars attached (and the 80# shelf in the TT)
Steer Axle is 3460 L/F 40" R/F 40 5/8"
Rear Axle is 3680 L/R 39 7/8" R/R 39 7/8"
Trailer is 4900
Net is 12040

Do these numbers and fender heights show improvement? I had hope to put more weight back onto the front axle, but with the addition of one washer and adding 80 lbs to the pass through, no change occurred to front axle weight.

Your thoughts??
