It wouldn't stop the axle from being replaced when it is needed in two or three decades, so what would be so bad?

I had to go back to check the photos to see if this Escape had a different suspension, since a Dexter Torflex can't have a round tube, and it does look pretty round from a distance. The corners have a relatively large radius, because it is thick-wall tubing, but it is "square" (four flat sides). All Torflex axles have a square tube: the rubber rods inside are arranged with one in each corner, and if that tube were round, they would just roll around instead of acting as springs. This - although not showing how rounded the corners look on the #10 model - is shown in the Torflex flyer.

Yes, that's how it works and the inner bars (which rotate but don't twist, but Dexter sometimes calls them torsion bars anyway) are square... but I was talking about the outer square tube (with rounded corners) which runs across the trailer between the mounting brackets.

Round or square, we are all talking about the same tube.

Several States require drag chains be attached to the trailer axle that has the brakes whenever conditions warrant use of chains on the tow vehicle. I think the "chains" are not link chains but rather a large variation of a motorcycle chain with fins projecting downward to increase drag--not sure though. Good news about the foam--thanks.

Humm, I'm not sure putting a drag chain attached to the trailer axle is a good idea. The freshwater tank is RIGHT there. I'd worry about the chain popping up and smacking the tank. YMMV

Actually drag chains are nothing but chains installed on your trailer when using chains on your tow vehicle. The effect is a drag caused by the trailer's brakes. It is not something dragged behind the unit which probably would be considered a road hazard. Think about what would happen if the chain got caught?


Question: People talk about drag chains. What are they talking about?
ANSWER: Drag chains are tire chains used on the trailer tires to enhance braking and control. California,
Oregon and Washington all require drag chains.

Jim, I'm really confused. Nick says:

Now are these tire chains or something hanging down off the axle? I still maintain, I'd be concerned about the water tank...

Chains are to be used on tires, not dragged underneath. When not in use they are either kept elsewhere or hanging down on the axle which is what you see a lot on trucks and emergency vehicles for the purpose of quick installation when needed. But they do not drag on the road, that would cause sparks and create a hazardous situation. You would not store chains that way on your travel trailer not would I even consider using chains on my travel trailer, if it is that bad I'm staying put.

I do think they are suspended from the axle and drag on the road. I share your concern about the water tank. Need to wait until the West coast opens for business for clarification

On tractor trailers the axles are high enough where chains will not drag on the road. You may not see them on the axle, hanging on the axle is just a way to store them while not being used. If they need to be used then you already have the inside chains connect and all you have to do is pull the cain taut on the tire outside. It is not that complicated if you use chains routinely. They also hang them on emergency vehicles,like fire engines, again for storage and it is a time saving routine when they have to respond to a call and need to have chains.
