Tires tilted (camber) outward on 274DBH

So I went out to an empty parking lot this morning to practice backing my trailer into spaces, and I noticed something very, very troubling. If you have a gander at the attached photos, when I turn the trailer, the trailer wheels tilt/camber outwards. This was when I was stopped, trying to back the trailer to my right (as I look forward in my truck). Pictures are of both sides.

Is this normal? Do I need to just tighten the lugs to 100 lb-ft and see if that helps? Are the axels FUBAR?

Any advice is appreciated. This is my first trailer, and it's still under warranty, so if I had to drag it back to get it repaired, no big deal, but I figured I'd ask the community here first for their take. Thanks!

Sorry they're upside-down... not sure what happened there, but you can still see the problem... just inverted.

If after you turn, pull forward and backward without turning and they will straighten out.

Yes, OldCoot, they do straighten back out when I straighten out the trailer. But I'm worried that they even do that in the first place... is that normal?

Very normal. To make a turn, tandem axle trailers have to slide or attempt to slide all 4 tires. The front tires slide under on one side and out on the other and the rear tires slide out on one side and under on the other. It is perfectly normal.

Yes it is normal. When you turn in a tight circle you put a huge amount of stress on the axles. One set has to slide across the pavement so something is going to twist. Remember your axle is held on by a spring that will move when you put force on it.

may be perfectly "Normal" but definitely bad for the tires. This sliding is what imparts 24% higher internal structural forces (Interply Shear) that is trying and too often succeeding in separating the steel belts from the tire carcass.

RV companies know this, or should know this if they had real automotive suspension engineers on payroll, but since they are never held accountable for their design decisions why should they care?

What gives the tires the 'twist/tilt' look is the leaf shackles pulling on one side and relaxing on the other, this helps 'turn' the unit with out putting a massive amount of strain on 'locked in place' axles/tires. A massive amount of pressure is put on the outside hub bearings when turning. Watch for wear at all shackles. Any sharp turning will slam the outside hub bearing into the castle nut and potentially cause the carter key to snap/fail. I would advise replacing the thin carter key that is used with a thicker one.

I also have a 274DBH. It does the same thing. They straighten out after the trailer straightens out. Perfectly normal. I was worried at first till I read about it.
Love my 274DBH!
Thanks for the advice Brother Les, I will replace the carter keys with bigger ones. My drive is a very sharp back in every time I come home. Did not realize the pressure that is put on the pins. Time for some bigger ones.

This is normal, the outside has to spin faster and since there is no differential with spider gears there is no compensation so the tilt is a byproduct of this. Similar thing happens on 4x4s with lockers, you get a "hop" or "skid".
