More options are available.

How many of our trailers would this apply to?

cons: expensive

pros: everything else...

I would love to have them, but cannot justify the expense.

I'm not sure the claims that a standard axle provide added strength to the trailer frame. Can anyone explain this? Are you sure the standard axle does not weaken thee frame compared to these Timbrens?
Other than the leaf springs being mounted a few feet apart to the frame and spreading the stresses that way, I dont see what stresses will be new.

You will need, maybe, to beef up the mounting area, you will need a mounting plate anyway, so that might be all that is needed.
You will need to weld or hire a trailer welder and hope they get it straight.
I once had a new torsion axle welded on and they welded it crooked, disaster. I should have walked away when the welder said he could not weld a bracket on. Dummy.

I was looking into them early last year. I was concerned about the possibility that mounting to a thin frame could cause them to rip loose with side to side forces against the tires, but I believe there is a square tube brace that could be added to tie them together to reduce those side to side forces.

With the square tube there is still better ground clearance than standard axles. There are square sockets on some them where I believe the square tube fits into. Can't find anything about the sq tubing on the Timbren web site, bit I'm shure I saw it.

I like the Timbrens because you can replace the rubber bushings if they wear out. You can't replace the rubber strips on a torsion axle and would have to replace the complete axle if the rubber wears out just on one side. The rubber strips are what makes the torsion suspension work. Rubber does age and wear out over time.

MORryde IS

I installed Morryde IS on a brand new 5th wheel. NOT CHEAP, but worth every penny. It made a huge improvement on towing.

MORryde IS, mentioned previously in this thread, requires it, and it's part of the install process.

Dexter makes their Torflex axles have a frame member that mounts up against the trailer frame to provide strength. The arms of the suspension are mounted on the end of this frame member.
These axles have been used on light, medium, heavy, and super-heavy duty trailers for years.
My snowmobile trailer has a Dexter Torflex axle to provide better snow clearance.

In the context of RV trailers, the average rv trailer frame would have to be designed much heavier and stiffer to resist the stresses imposed by this product. Nothing wrong with the product itself, IMO.
