No, you don’t need to re-weigh anything.
You have about 1000lb tongue weight and a 5700lb trailer.
Just do the math. It’s only addition and subtraction
Looks like about perfect loading for a half ton.
Carry on and don’t make it a rvnet science project.....the geezers here will be having you add the weight of every half rack of beer you pack and deduct if you’ve had a bowel movement since weighing the last time!


This X2!! I run my 1/2ton which has a GVWR of 7050 at 7000 give or take 100lbs or so. Weighted it twice once for weekend and for a week trip always hovers around 7000. Same with the trailer have a sure line tongue weight scale always 15-17% tongue weight. Love how rock steady it tows.
Don't need to measure down to the ounce.

Your front axle has more weight with the WDS than it does with no trailer attached. That shouldn't happen. You need to reduce the WDS tension some. Yes, I know it isn't a LOT more, but it shouldn't be more, at all.

You reduce tongue weight by shifting where you load stuff in/on the trailer. Move stuff from in front of the trailer axles to behind the trailer axles.

According to those weights, your tongue weight is 1040#, but 15% of the trailer weight is 700#. So, 700# should be the max for tongue weight. After you get the tongue weight where it needs to be, be sure you aren't using WDS to put more weight on the front axle than the truck has with no trailer.

You have returned the TV's front axle weight almost to normal without anything hooked up...20 lbs (3,040 vs 3,020) Better than many...

Check your TV's manual on that, as the old rule of thumb of even drop is no more because the OEMs have all changed their suspensions so much

Some say to return to within XXX lbs of unhooked weight

Some say to return the front height to +/- XX inches of unhooked height

I try to NOT ever say 'you are good for it', but the finished setup orientation and reference your manual. What works for me, is not like a one size fits all sock

Have seen folks run in circles dialing in this, changing that, etc because it worked for someone else's TV

I hate to say it, hes pretty good on weight. And i still say lt tires will help some. But in the end its a bigger TT and there will be some assosiations that come with that. You could get lt tires, bigger suspention in the back but it will still be work. Just the way it is. ( i still think the tires will help a lot). The guys that say they have a half ton pick up and tow 6000lbs TT and dont feel it are not atually telling the whole story.

According to a calculator I found online, my tongue weight is 18%. I think everybody agrees this is too high.

How do I bring this down?

As suggested, I increased my truck tire pressure to 50. For the short highway drive to the weight station, it seemed to help some but don't think it is the total solution.

Several have mentioned the equalizer as the best system. I might be interested in switching. My Blue Ox uses chains for connection and it is very difficult to get it as tight as the manufacturer recommends. I have to raise the hitch way high to get it latched on and off. Even at that it requires a lot of strength of which I'm not sure I will have enough of everyday.


I ran the Reese Dual Cam system on mine and was very happy with it. No sway and easy to hook up.

Question to the OP. What have you towed before?
It’s a trailer. Heavy tongue weight (expected. Load 1000lbs in the back and report back to us.
Or get over the fact that pulling a trailer doesn’t feel like driving a buick.
Sheesh
You’re good

Sounds like my trailer with my 1/2 ton. Do I feel it? yes the truck accelerates and slows longer than no trailer. Can I drive with one hand ? yes! Does it sway? NO! Does it suck push with semis passing? depends on their passing speed. Do I need a bigger truck? Nope!! It's a pleasure to tow. Could be because my 1/2 ton runs about 7000lbs (it's gross is 7050) and the camper is only 6500.

OK I haven't been on here in a while and I skimmed the replies. I had that squirrely feeling with my Blue Ox and just couldn't get it tuned in. I talked with Blue Ox several times and finally a tech at Blue Ox said in some rare tuck/trailer combos the trucks built in traction control/anti sway fought the Blue Ox set up. He suggested shutting off the traction control. I did it and now it's the best towing trailer that I've ever towed.

I never thought of the traction control being a problem. I will give it a try...thanks!
