I’m having trouble with payload for a RV, help?

[Josh00333]

Well, now I'm concerned...
Went through a CAT scale today with a full tank, empty bed, no passenger, and the Jeep weighed in at 5080lbs. Which, based on the door sticker GVWR of 5800lbs, leaves me with 720lbs of payload.
Figure the wife takes another 200lbs, the camper loaded up with the bikes on the tongue carrier is 500lbs tongue weight and...
I got nothin' left man...

Now here's a weird bit...
Last year, I scaled the Jeep and camper on a CAT scale. Before heading out, I got the tongue weight with our tongue scale (500lbs,) and if I'm adding up the numbers right...
The Jeep without the camper would've weight 5080lbs. WTF?

The *ONLY* change to the Jeep between then and now has been the removal of the front bumper, which was replaced with a Metalcloak mid-width and a winch.
Just for funsies, if anyone wants to check my math, here's the raw numbers:

Date	Steer	Drive	Trailer	Gross
7/12/2023	2440	3140	3160	8740
5/3/2024	2780	2300	0	5080

From your numbers your tongue weight is 500, but as you noted the scales are a year apart and mods different.

As Papa noted there is a little scale error.

Fill up, scale truck, go pick up the trailer, dump everything gray black and fresh. I scale with full propane as well.

Then drive back and rescale (top off if it’s a few miles). This gets you the most accurate numbers. And apples to apples.

I did this when I bought my rig, I‘ll do it again this year, been a couple years and I’ve added mods and stuff to the tuck and trailer.

Our first camping trip is coming up in a couple weeks, we're not going far (it's a "did anything break over the winter" sort of trip) and there's a truck stop with a CAT scale on the way, we're going to swing through and weigh then, too.
