Anyone know why the caulk around the inside metal frame of front bed keeps cracking. When we picked the camper up from the dealership brand new it was cracked. The dealership recaulked right over the old and we took it home 2 hours later. Our first trip this past weekend and I noticed it's cracked all along the top again. Is this normal? What caulk should we be using to reseal. I have dicor non-self leveling from our previous PUP. This isn't a picture of my camper but if it was the arrows are pointing to were the caulk problems are at.
