We have a 2013 Sanibel we purchased August 2012. We have pulled it around 10k miles now.
I started to notice that the caulk between the bottom of the overhang and the side wall was pushing out and separating on both sides but most predominatly on the passenger side. I'm not sure when this started but I noticed the caulk coming out over a year ago.
I had the Sanibel in for warranty work in Elkhart last week and before I could ask about the caulk issue (I thought it was a routine maintenance issue and I just wanted to know how to address it) the repair shop owner told me I had an "upper Frame Flex problem that needed to be repaired. He said he has done many Sanibels in the past year and he had one in the shop he was doing at the time. He said the repair takes about 5 days to do and required the bed slide, dresser, and the front fibreglass cap to be removed.
I am still waiting on a schedule to have the repair done.
Now that I know about the issue I have watched this area when I hitch up to the truck. The bottom of the overhang actually moves up about 1/2 an inch when the weight of the RV is placed onto the truck.
Are there others out there with this problem? I also want to alert others of the problem if they don't know already.
I attached a picture below to show what to look for.
The area that moves is the area between the bottom of the decal and the trim on the bottom of the overhang.
Note that the vertical trim piece under the bedroom slide is loose. It actually pushes into the slide when the weight is put onto the truck.
