Nothing cool here, I was trying to direct the OP to sites that members of were far more apt to have the IRV-66 installed in their RV's
The IRV-66 is a typical (and overpriced) option found in current production stick-built trailers such as the Flagstaff. There was one in the sticky we bought for a now ex step-sons family, and I couldn't believe the MSRP on the option. Here's a link to Flagstaff Trailers by Forest River.

Much like new cars, dealers order RV's loaded up with these options and pass the options on to the buyers via heavy discounting of the imaginary MSRP. I really doubt if this is an item one would find in an FGRV or that any one would add and, as was mentioned, it was thought that the problem might be related to the installation.
Here's a link to them:

BTW: In as much as it is a 2015 trailer this might be a warranty problem for the selling dealer to deal with. We had to take the above mentioned sticky back several times for repairs and re-repairs while in warranty.
