Used to have a 2013 Fuzion 342. Had some funky stuff going on around the pin box area and skirting around it. Along the outside it also looked like there was a gap between the wall and the floor that had started to widen. You could see where it had dropped down from where the old caulk was. I re-caulked it and kept and eye on it for 1.5 years and didn't see it happen again, but it just never sat right with me. Eventually sold the truck and trailer and moved up in house. Hope the ole Fuzion isn't giving the new owner any problems, besides the fading front cap issue and the usual other little things that were always popping up.
