Front seam dent/broken seal

[CanCamper-FRF]

We have a 2012 Forest River Surveyor Anniversary Ed. We bought it second hand last summer. Most people leave their RVs at the park during the winter after winterizing them. We show shoed into the camper several times over the winter to check on it and the last visit we noticed a dent/break in the front seam, on the bottom, the area behind hitch where the “front meets the bottom” (sorry it’s not a good description). I’ll try to add picture. Anyway, my husband went back the next day and removed the steam of ice that was going into it and caulked it (which was hard bc the caulking keep freezing). Anyway, that held up over the winter, but wondering if any else experienced this and also wondering where exactly any water would gave dripped or collected if it did get inside at that particular seam. The red dot on one of the pics shows the exact spot/seam. Thoughts?
