I think I can speak for many when I say, I don't give a hoot what AS recommends and I will do what I think is okay without consulting with AS first. I get to use my brain and I get to ignore the unfounded paranoia of others. (Life lesson)

I would not mount anything to the bumper of my 23FB which left the factory with less than 10% TWR. The only model I know like this. (Just the facts)

Whose? 😂

Most folks realize that JC just's pins the tail on the donkey regarding TW.

Everyone has a right to their own opinions and paranoia.

Now I have to include weight for a non-existent bumper as well? You are sure hard to please...but ok. Before you say anything more, I am going to be proactive and commit to no longer traveling with my unicorn in the the bathroom. That guy does nothing but eat Skittles and fart rainbows all day. Can't trust a creature like that.

Your work is done here sir. My life has been changed.

I think he was arguing FOR your modification, not against. When he said "you" he did not mean "you" the OP he meant "you" some other poster. That's how I read it at least.

I’ve seen (and participated in) some doosey threads here, but this one takes the cake. OP, for peace of mind you might want to measure tongue weight. If you’re in the 10-15 % range, you’re good to go.
Looks like a nice setup.

rmkrum · 03-20-2019, 06:52 PM

Tongue weight being in the right (10-15%) is critical. Sway easily starts if that is not right. Don’t guess. Weigh it.

While tongue weight is important it is not as important as having a tow vehicle that is beefy enough to keep the trailer from swaying to begin with.

Today...beefey toe vehicles prevent sway. 😂
Only if you have the beef...👎

These 3/4 tons must not be beefy enough as there's plenty of threads trying to figure out how to keep them from swaying.

So... the beef does sway, I always thought it was the Airstream, got it, the beef is so beefie you don't even notice the sway..."it toes like it's not even there"😂

I disagree. We’ve even seen pictures posted in forums of accidents where the trailer flipped the “beefy tow vehicle” on its roof.

I do not agree.

Trailer sway is the fish tailing of the trailer while pivoting on the ball. The trailer does not care what the ball is attached to as sway is something that the trailer does. Some hitches lock the trailer inline with the trailer which has proven very effective. For the rest of us sway can happen. If you have a big heavy duty truck, your rig can resist the sway because of it's footprint and it's weight. The expression, it tows like it isn't there is often used by the big truck towers, because if it is swaying, they can not feel it. The size and weight of the big truck has a down size too. The truck can resist the sway action of the trailer for a limited amount. When the forces of sway get too big they can overpower the biggest of trucks. We have all seen YouTube videos of a trailer going ide to side and flipping a large truck.

With a smaller truck, suv or car the forces of sway will be felt much sooner and the driver can take appropriate action to bring the rig back under control.

Based on this, one might say that a smaller TV is in some ways safer that that big truck.

This provides a good illustration of car/trailer stability based on weight distribution in the trailer. Note that in either case there was sway caused by some perturbation (in real life it could be a gust of wind). However the difference is stability: will the sway dampen out or increase out of control?
Also keep in mind that it’s not just how much weight you have behind the trailer wheels- it’s also the location of the weight. 100 lbs 10’ to the rear of the trailer axle is equivalent to 1000 lbs 1’ to the rear. That is why tongue weight is important.

ROBERTSUNRUS · 03-21-2019, 10:52 PM

Hi, I hate that video; Not realistic at all and what trailer has the axle mounted dead center? It would sway with out any of the weights.

rmkrum · 03-22-2019, 12:21 AM

I see it as clearly depicting the consequences of one of the many possible trailer load distribution issues. Too much weight behind the axle and not enough tongue weight is a for sure sway inducer scenario.

Fair_Enough · 03-22-2019, 05:08 AM

A big truck can not prevent trailer sway. Period. Old wives tale.
Bigger truck is less affected by a little sway and could go unnoticed for the most part. But if things are setup wrong, sway it will.
Another old wives tale while I’m meddlin’ is that you need a big truck to stop a trailer. That’s why trailers have brakes. Need flash, they stop their own inertia unless something is amiss. These are “reasons” a guy tells wife so he can talk her into a big truck. Wives beware.

I doubt a small generator hanging off the rear bumper is going to make a big difference, though that would be the worst location for a heavy load. Not only do you have to keep a certain amount of weight on the tongue to prevent sway but the distance of the load to the rear axle (the sway pivot point) makes a big difference. The load moment of inertia increases with the square of the distance from the pivot. If you do have heavy stuff to carry then try to place it over the trailer axles.

RandyNH · 03-22-2019, 07:12 AM

Just make sure you always do a walk around, at the gas station, make sure it's still there after going over the entry slope. And watch in your mirrors when leaving.

What's that shark fin on the bottom? That bolt on part (with the scraper edge) and the nuts doesn't look like it will sustain too many strikes. Or is it all just photo perspective?

Maybe install one of these back there somewhere

I was the OP on this and my issue was NOT sway. I have none at all. Issue was bent bars which BO are replacing.
