Fresh Water Tank Support Failure

I was prepping my 2013 Rockwood ROO 23rs for this camping season when I got back to the fresh water tank.

Has anyone seen this type of structural failure on a new (1 season) camper?

I am taking it in on Monday to have the dealer look at it and hoping that it will be covered by the factory.

I know our tank will sag under the load of the water but the supports have not bent like that. Was the tank empty over the winter?

I think you nailed it.

Pretty much the only way it would bend like that (longitudinally) (IMO of course).

I could buy rough roads with a full tank if it was a cross member; but not the long one.

Tank was empty and drain plug was removed for the winter.

I noticed it when I went to flush the tank. I refilled the tank and went to remove the drain plug. It was then I noticed it. I don't know if it occurred last season some time nor how long it has been like this.

Since it a 2013, I assume you bought it new.

Is the under belly exposed or is there a Coreplast cover over it?

If it is exposed, you could have hit road trash (like a section of truck tire) that did the damage, and never noticed it till now.

With a cover, you would have noticed the damage as soon as you pulled into camp (or home).

To me, it appears that the center bar on the tank was pushed down by the weight of the tank(presumably filled with water while traveling), and pulled the cross member down. I would think that a tank that size would have a few more supports under it. I would have them replace it with a "structural" angle iron cross member, and not just "bent" steel.

Having worked in the steel fab industry for 13 yrs my opinion is that that this would not be caused by road trash. The angle is bent straight down. Road trash would have bent it back or up. It could not go back because there is a cross support in the middle of the angle. Whatever caused this pushed down on that angle. Any road trash would have also put marks of the water tank but from the way the photo is taken you can not tell if there are marks. It looks like the tank itself may be bowed down a bit. Maybe this is the design to create a low spot from draining.

That's just my 2 cents. I'll be interested to see what the dealer says was the cause. Good luck.

I would have thought that bowing of the tank bottom would have damaged that cross bar and rotated the longitudinal support towards the tank, but I can certainly see your point.
It is odd; no doubt.

Yes, that makes sense also. I guess the piece that bent was the weaker of the 2 for whatever reason. There may have been another force involved that is not obvious from the picture since it is only from 1 point of view.

To me, it still appears that the center of the tank is bellied down. The weight of that tank bouncing would almost definitely bend a 6' piece of bent angled steel.
