We bought our 2552 used & knew little about the equipment that was installed by PC or the 1st owner. The obvious items I could see. So, I ordered a copy of the build sheet. One thing stood out that I know nothing about, ie the build sheet shows a #35401 Gas Grill Hook Up with Quick Disconnect. I have no need for the hook up but would like to know what it looks like. I have seen hook ups on other RVs that are normally in a convenient location for use. Here's a picture of my propane tank----maybe someone can point to the hook up. Thanks, Chuck
