Big Bubble on top front

[tooth ferry]

I know this could be in "was this you" section but I thought more people might see it here. Friday 3/26/21 I saw a Montana on I-20 near the Ga-Ala state line westbound at about 1 or 2 PM. I could not tell year or model in this quick sighting and the only real identifying detail I saw was that there was a step ladder fastened on to the roof access ladder. The real situation that I wished I could have told the driver was that there was a very large section of the roof from the front edge almost all the width of the trailer that was blown up into a very large bubble probably 18 to 24 inches high. If this could have been you check your roof, or if not , be on the watch for a Montana with a step ladder on the back and any saggy front roof edge.
