I installed some angle iron between the supports of the storage undercarriage
Seems. To have helped and made my brain not think so much about the eventual outcome.
I suggest using aluminum angle bar can get at Home Depot and attached with sheet metal screws.
I attached the slide roller fittings with spacers and it has definitely improved the structure.
Hope you can see in the picture.
Still awaiting THOR’s response to the deterioration and delamination of the floors.
And I have been the nicest of customer hoping to get a positive response.
