I went out to the RV today and this is what I found. It seems one of the main doors has cracked.. The other door up at the front is fine but the one in the back is not. Here's a pic. What could of mad...
I would not think along the line of heat or cold… think more defective materials… Consider the 2 doors were exposed to the same weather conditions, it doesn’t appear to be delamination caused by moisture, and it doesn’t appear to have been tampered with…
When discussing this with the dealer or the door mfg. don’t even entertain the heat/cold as an issue… the door should withstand either of those conditions to the extreme… be polite but firm on that…
