Finally weighed our trailer and TV....

We were able to weigh our set up last week, and this is what we came up with.

Weird thing was how almost to the pound, we were at the exact max for the truck and the trailer. We were surprised, because we thought we'd have plenty of room to spare.

With that said, we feel like the trailer pulls wonderfully and that we have plenty of power with the truck. We pay attention to the rpms while going up hill and down hill, and the engine never seems to be stressed.

Over all, we're happy. Just curious if any of you more experienced folks have any comments or insights on our info below. Want to be sure we're not missing any pieces of the puzzle.


Pro Pride Hitch

2017 F150 Eco Boost specs from sticker on driver's door
Gross Axle Weight Rating, front 3525
Gross Axle Weight Rating, rear 3800
Gross Vehicle Weight Rating 7000
Gross Combined Weight Rating 1634

2018 23CB International Serenity factory specs
Unit base weight 4761
Maximum trailer capacity 6000
Hitch Weight 664

Our actual weights: Truck fully loaded with passengers and cargo. No trailer.
truck Front axle 3300
truck Rear Axle 3000
Total truck 6300

Our actual weights: Truck with trailer attached
truck Front axle 3300
truck rear axle 3650
total truck 6950

Our actual weights: Trailer only, while hitched to truck
Trailer 5300

Our conclusions, which seemed to make sense to us, but not really sure if this is correct way of thinking.....
The weight of the truck went up by 650 lbs with the trailer hitched, and therefore, we concluded that 650 was the tongue weight. And, that would put our total trailer weight at 5950. And that would put our tongue weight at 11%.

I think your “Gross Combinrd Weigjt Rating” (GCWR) is incorrect at 1634 lbs. GCWR would be much higher. The 1634 number looks more like “Payload”.
Is the 4761 trailer base weight from a brochure, or the sticker on the front left side of your actual Airstream? Are you towing with a big load of water?
As you have shown, can be surprising how heavy the final towed load is.

My bad....you are correct...1634 is PAYLOAD.

The 4761 trailer base weight is from brochure. Where is the sticker you mentioned? On outside? Inside trailer door sticker says not to exceed 900 lbs cargo.

That was with fresh water tank with only 4-5 gallons.

Dialing in our ProPride

2018 F150 3.5L, 3.55
2018 27FBTwin
ProPride 3P1400

A 12 mile tow to the scales in 20 mile per hour cross wind went well. Seemed a bit light in the front…in fact we are 200 pounds light on the front axle. Sean at ProPride suggested 9.5" jack heights and one more washer. Will weigh again tomorrow.

That’s a lot of tongue weight for a (5,400lb +1,100lb) = 6,500lb trailer. 17%. Consider your loading.

Your trailer should sit level within 1/2” front-to-rear. And certainly not tongue high.

If 9.0” jack height is doing a better job transferring weight back to the front axle of the TV then you should drop the ball to get that trailer level.

Interesting. I measure my wheel wells since I don’t have a scale to go to. I also put a level in the trailer to see how level it is. My trailer runs slightly tongue low when I tow, and my wheel wells are the same height off the ground. And I run a Propride hitch. How many washers do you have in? I have 4. I also put my jacks up to about 7 1/2”. It seems a 9.5” jack height would really cause the tongue to be too high. Good information. Is that an F150?

The jack height on a ProPride relates only to the amount of WD bar tension, not the tongue height. The jacks directly adjust the loading on the front axle.

Tongue height is set by the bolts that adjust the two-piece stinger height. The washers adjust the ‘bend’ in the stinger and affect pre-load on the WD bars, usually.

"factory specs Hitch Weight 664"...

No such thing in the real world.

Our 'factory' TW 860 lbs.

TW=weight at the tongue un-hitched.

You are right. Weighed today and I'm -50 lbs on the front axle (3350 down to 3300), rear wheels up 1000 from 2250 to 3250. Pulls great. I am about 1-1/4" difference front to back (17-1/2 front; 16-1/4 back) and may drop the hitch down one hole. But the distance from the ground to the tension bars is tight and we have very uneven private gravel driveway for 1/2 mile… so I hesitate to change that right now. Your thoughts?

Check the factory sticker on the lower roadside front.
Or call Airstream with your VIN number.

My thoughts are that you should tow with a level (or near level) trailer. Being tongue high means, at a minimum, you run a greater risk of bottoming out the bumper skid plates when transitioning through a dip or making a change from level ground up a grade.

If you need to go up and down that driveway routinely, consider getting a lift kit for your AS. Have a search of the forums for lots more data

Setting it up for a half mile at slow speed vs 500 miles at highway speed would not be something I'd recommend. Nose down vs nose up, any amount, is more desirable to control sway. I would get yourself level or nose down, then figure your path out of your driveway and grade what needs it.

Wow, that's hugely different from what we got when we weighed ours for the Texas registration.

Ours was a really simplistic approach: the F150 on one scale and the 23D on the other. All hooked up, the CAT Scale put the truck at 5,680 pounds and the trailer at 4,680 pounds.
