Leak under my refrigerator slideout

I'm new to this great forum that's chalked full of information. We just bought a 2014 Berkshire 400QL (1 week ago) and after I attached the water hose, we started getting a pretty good leak under the refrigerator slide. I cannot see where it is leaking. Wondering if anyone had any ideas before I drive it 100 miles back to the dealer.

I'm sure this was covered before, but I've only had time to read to page 9 on this forum.
