All things fatigue...even humans...
The suspension (tires, springs, control arms, shocks, bushings, etc) are all
good for +millions of 'cycles' and will fatigue/fail at some time.
You can accelerate that failure point by pushing their limits/ratings. This can
be speed, weight, harsh terrain, etc
Ditto any human
But...I do NOT think any component fatigue...as TV components do NOT heal themselves
like a human can with a good night's sleep and good food
some jet wash movement was noted
This comment says it all for me...
Say this often: "all things designed/engineered are NOT for the good days out
there, but for the worst day out there when Mr Murphy crosses your path
Either you have the proper sized components and properly setup it up, or not.
There will be no time to go back to the store for bigger/better components nor
re-setup
Either it is there spot on or not"
I suspect you encountered whatever ambient situation and/or terrain that pushed
your setup over the limits of it's ability to manage.
Sizing is critical at the limits and that is to manhandle the setup
The vehicle is rated for 10,500lbs
Yes, that is the rating, but there is fine print for that specification
That fine print says 'curb' vehicle (stripper model) and one 150 lb
driver. Some times full fluids, other times half a tank...etc
If your TV has more than one seat belt filled and each weighs more
than 150 lbs...and...you have cargo...that 10,500 ratings is NOT for
your vehicle
All of your options over a 'curb' (AKA stripper model) takes away from
the 10,500 rating, pound for pound. Ditto passengers. Ditto cargo, etc
AND...if you loaded up to your GVWR before hooking up...your TV has
no more rating for the tongue weight !!! :E
Therefore ZERO rating for any trailer
