It's all about the cost. They could build a light weight trailer, but many people won't pay for it. I went out of my way to find one of the older livinlites because the newer ones after Thor took over used plastic floors instead of aluminum! So the companys old "all aluminum no wood" motto became "no wood" . In truth it wasn't all aluminum to begin with (canvas, axle, tire battery, steps, were not aluminum obviously) but still...As scary as it sounds, it does not surprise me. Seeing my parents trailer and lack of floor joists and using foam as a floor, manufacturers are taking way too many shortcuts in the name of weight. Even if it comes at the cost of critical support. My parents floor was caving in on their camper and both the dealer and manufacturer was essentially saying not their problem. It’s sad, scary, and down right infuriating that manufacturers are not held accountable for these shortcuts. It’s not just one brand but all of them it seems. They all are trying to brag of how light weight a camper is, but at what cost? What shortcuts did they take?
Yes but in the video, that fellow claimed all the breaks have been in the webbing. But yes the flanges are to light. Maybe we could sell enforcement kits for them??It's not the webbing being too thin. Thin webs are ok as long as the torsional loads don't deflect between the top flange and the bottom flange.
The issue is that the bottom flange is stretching, exceeding it's tensile strength.
The easiest solution is just to get some 1/4" strips and weld it onto the bottom flange. It can also be boxed but realistically the bottom flange must be strengthened.
The other short term choice is to just cut jam in some wood into the channel.
There are definite design choices made. Ground clearance, cost, and even how much tongue weight is a big factor.
In the first vid it's the flanges. In the second it's a c channel with badly designed webbing, basically all forces go into that one spot. Was probably beating up the c channel, so they came up with this slat of iron to try and move the stress, but right to the webbing. There seems to limited space on this design so they are kinda forced to use this block looking part.Yes but in the video, that fellow claimed all the breaks have been in the webbing.
