2020 Eagle 321RSTS weight info

[SB_James]

We finally had our first trip in the new RV, and on the way to the park we stopped at a Flying J and weighed our rig. I put about 15 gallons in the fresh tank and we had it loaded for a weekend trip. The numbers look good, but I was surprised at the truck front axle load. I have the Blue Ox Super Ride hitch, which puts the king pin slightly ahead of the goose ball / rear axle. Here are the numbers:

Truck only:
FA: 4,660 lbs
RA: 3,480 lbs

Truck & 5th wheel:
FA: 4,820 lbs
RA: 5,840 lbs
TA: 9,640 lbs
CW: 20,300 lbs

5th wheel:
Total: 12,360 lbs
Pin: 2,720 lbs (22%)

So, I have added 360 lbs to the front axle, and 2,360 to the rear. I am also over the "sticker GVWR" of my truck by 660 lbs, but within the axle ratings.

I think I'm okay with these numbers for now, but before heading out West, I think I'll be looking to upgrade to a 1 ton, just to have some extra margin (plus better engine braking!)

Okay, now I have to go and look at mines again just to compare your weight and mines.



So now how did you come up with the total and the pin weight?

According to your numbers, you've only added 160 lbs to your front axle which is IMHO a lot more than what I would have expected.

That's good, you want added weight on the steer. Definitely don't want less.

OOPS! You're right. Must've fat-fingered my spreadsheet entry (I typed in 4460 instead of 4660 )

So that does some other number-changing to my post:

Pin Weight: 2,520 lbs (20.7%)
5er Weight: 12,160 lbs

Thanks for the correction!

You will need to weigh both truck and trailer, then drop the trailer and re-weigh just your truck.

Then to find pin weight, subtract the truck-only axle weights from the hitched axle weights. Add the 2 numbers and that equals your pin weight. Don't add the front axle value if the value is negative. (If your kingpin is behind your rear axle the front weight may be negative - meaning a lighter front axle weight when hitched.)

To find the total trailer weight, just add the trailer axle weight to the pin weight you calculated.

I hope that makes sense to you, Big1. From my memory of your post, your trailer is definitely heavier than mine.

Now that AKRUEBBE pointed out my bad arithmetic, I am much more comfortable with the slightly higher front axle weight.

You should only be concerned if your axle weight is close to max or over. Or you have less than what you started with.

We have a 2019 321..started with a 250 diesel, recently upgraded to a 350 diesel....feel a lot more comfortable with the larger capacity...

You’re in about the same boat as myself. I’m over GVWR with a diesel Chevy 2500. Added Sumo Springs for a little help. They’re perfect. Today, we came up through Cimmaron canyon and into northern NM. Lots of xwind. Did just fine. Then, we wound our way up from Colorado Springs to 9500’ feet at a state park. Again, no issue. For me, this was a sort of proving run to be sure I didn’t need to run to a dealer and trade for a SRW 3500.

Good info, Txloser. My airbags are invaluable in the ride height and comfort departments.

The truck tows really well. We were doing 70 on I-75 and 18 wheelers passing us were almost unnoticed.

My only wish is for more horsepower for climbing grades. One day I plan to upgrade to either the 6.7 Powerstroke or Cummins, but I like not having a truck payment every month [emoji16]

I don't see how because I don't have a lot of stuff but I guess I does but anyway yeah I will weight it again.

Well today I went and re-weight my truck with most of all the stuff I would have when travel. So I added everything up again going off my total and my pin weight is 2920 lbs and my total truck and 5th wheel is 12,600 lbs.

The other weight that I didn't have inside my truck was my backpack with probably weight 5-10 lbs.

Big1, sounds like you're just fine.

[Big1]

Yes sir I am good like I thought I would be, it just that I didn't have everything inside my truck for camping, there was a few small light items that was in there but I'm good with that.

This is my new one.
Steer Axle 5180 lbs.
Drive Axle 3720 lbs.
Total Weight 8900 lbs.


Also so since I took my wife with me and the first weight was 8200 lbs and the second one change to 8900 lbs, she told me that she don't weight that much, lol, I told her that I had a full tank of fuel and she still didn't go for that so I just shut my mouth, lol.
