My weights...for anyone interested in these things.

Finally did the weighing thing at the CAT scales today. On our way home from 4 day trip so pretty well loaded. 2007 Dodge 2500 diesel and 1988 25' Excella. Reese straight line with 800 lb bars. full fresh water tank. 1 full, 1 empty propane. through hitched then with the truck unhitched. I have summarized below.

Trailer 6320
Truck 7880

Trailer placard GVW 6800. Axle GW 3200 lbs per axle.

Trailer axle carries 5520 hitched
Truck carries 800 lb of trailer wt.

Truck front axle not hitched: 4460
Truck front axle hitched: 4300

Truck rear axle not hitched: 3420
Truck rear axle hitched: 4380

The interesting thing to me is the off load of 160 lbs on the front. I adjusted the hitch so that the front fender height was returned to the unloaded height. But with only 1 inch of travel that is a hard measurement to make.

I have the hitch turned down almost, but not quite, fully and run 4 links between the bar and the lift.

I think the truck drives well. I have tried 5 links and thought the truck felt a little loose. Does anyone see any advantage to try to move more wt up front with the hitch?

We probably carry another 150 lbs of food and propane when topped off. Some will be on axle, some under the gaucho, and 30 more lbs on the tongue with the propane filled. I am pleased with the weight under the rated load. I run the 15" Michlen XL tires so I like the low axle wt.

Do not know the dry wt of the truck. I have a fiberglass low top and probably 300 lbs of tools, generator, slide box, grill, etc in it. I love the 2500, but with the 800 lb load on the truck I think I could pull it easily with a 1/2 ton too.

Yes there are some that will say you are light in the front end. But with that truck you are fine .

If you really want to get a closer measurement on the front fender put a strip of masking tape on the fender an mark a measurement from ground on that tape through the center of the wheel After hooking up and without moving the truck remeasure to that line. Ideally on a lighter truck you would shoot for the same measurement. Anything greater you are lighter, anything less you have put TOO much weight on the front end.

Again with a 2500 you are fine with what you have now.

If you are at the limit of the tilt on you hitch head or if the trunnions ware to a point that you need additional weigh to the front axle you can place a plate under the hanger brackets to raise them and get the adjustment you need. I use 3/8 aluminum on top of the trailer frame under the hangers. This can postpone a complete readjustment of the hitch if you are on the road and need some additional weight moved forward.

Thanks Howie. Never thought of raising the chain hangers.

It seems that your weight distribution is moving a lot more than 160 to the front axle. If you just drop the trailer on the hitch, you will take a lot of weight off the front axle. Your WD then restored all of that, and then an additional 160.

(This from someone who spent all summer last year saying, "I really should stop at the scales" but never did. This spring, I am saying the same thing. And I might just do this year).

The WD hitch returned weight to the front, but retuned 160 less than the unhitched weight, not 160 more.

By measurement, the front end goes up 1 inch with the trailer and not WD. Adding the WD bars restores the front to almost the original height. But it is 160 lighter than without the trailer. I did not weight the tongue or the truck with the trailer but without the WD.

I have pulled this rig for 6 years and lots of miles. I did not feel I had to weigh it. Just curious.

I believe that you have found the same as me, if you remove more that about 150 lbs from the front of our trucks (2006 Ram here) they start to drive funny.

Ron Gratz Weight Chart


The question is load transfer. The above chart makes cross-checks easy, but data is incomplete thus far for this thread. Make all readings same day for better analysis. Best analysis is wheel-by-wheel according to tire industry. Try to even out across axle-loads. TV tire pressure is also at stake (per vehicle manufacturer guidelines; use 2008 or '09 door placard readings for latest revisions on correct pressure range).

Is the truck 4WD or 2WD? Either may need front end and/or steering work to bring them to par. Don't blame WDH until front end and steering are verified as ideal.

160-lbs may not seem like much, but better to sort out problems potential and real in re front end / steering and corrected tire pressures as even small amounts or changes "might" give rise to response concerns otherwise.

Better shocks always make a difference (KONI PSD if 4WD) and new anti-roll bar links may be needed.

800-lb bars are the last question I'd ask. A separate TW reading gives that context.

I went to the CAT scales for the first time.
My weights:
TV and TT, with WD applied
FA1 4,720
RA1 4,640
TT1 7,260
Gross Combined 16,620
TV and TT, without WD
FA2 4,360
RA2 5,160
TT2 7,100
TV solo
FA3 4,780
RA3 3,680
Truck Gross-Solo 8,460

The truck solo weighed more than I thought. I was pleased with the weight distribution - of hitch weight of 1,060, I moved 360 to the front axle and 160 to the trailer, leaving 540 on the rear axle. The WD restored the front axle to its solo weight (almost).

My TV is a 2014 GMC Sierra 2500, Crew Cab, Standard Bed, Duramax Diesel, 4x4. My trailer is 2013 Airstream Flying Cloud 30, hitch is a Hensley, and I was loaded for camp, full fresh water and propane. BW and GW tanks empty.

When measuring the TV, the front was unchanged with the trailer, the rear was down an inch. The trailer was pretty level, a couple of inches lower in the front compared to the rear.

Comparison to Capacities
Actual Weight Capacity Delta percent used
TV FA 4,720 5,200 480 91%
TV RA 4,640 6,200 1,560 75%
GVWR 9,360 10,000 640 94%
GCWR 16,620 24,500 7,880 68%
Hitch 1,060 1,500 440 71%
TV Tires - FA per tire 2,360 3,195 835 74%
TV Tires - RA per tire 2,320 3,195 875 73%
TT Gross 8,160 8,800 640 93%
TT Axles 3,630 4,400 770 83%
TT Tires - per tire 1,815 1,985 170 91%

The guy at the CAT scales charged me $10 for each weigh, a total of $30. I explained that weighing #2 and #3 were just refinements and should only cost $1 or $2, but he was having none of that. He was also very insistent on a company name and a truck number before he gave me the yellow weigh tickets. And we had a bit of a false start at first because I didn't see the call button - and when I did find the button, I had to use a step ladder to reach it! (the step ladder did not make its way back into the truck for the weights - need to add 9 pounds for that). It look an hour and 10 minutes, but I am glad I finally took a trip to the scales to see what I actually weigh.

Congrats. Yes, I think your CAT operator didn't understand the rules. Was it a private operation or an actual CAT branded scale?

it was a CAT scale at a Marathon gas station/truck stop.
And the truck stop was busy the whole time I was there - 4 or 5 rigs fueling.

From catscale.com FAQs:


What is CAT Scale’s reweigh policy?
A reweigh for $2.00 may be charged, after the first weigh, if all of the following are true:

Same vehicle (tractor and trailer),
Full price ticket is presented by the customer and its number is recorded on the reweigh ticket,
Reweigh must be from the same scale as the full priced ticket,
Reweigh must be within 24 hours of the full priced ticket.

On edit: by the way, I give my WBCCI# for both my tractor and trailer number and company is "self" (though I've been tempted to say, "Tin Goat Adventures" :-) )
