Help Stoltzfus in PA sold us a brand new leaking camper!

We'll be picking up the trailer tomorrow from Stoltzfus. We're a bit worried because today we spoke with the GM and found out that they never did the pressure test. They said they don't have the machine that can do that, and most dealers don't use the machines because they don't work well anyway. They said they use a hose to complete the pressure test, basically just spraying the camper. They also said we should expect to see some water when there is a heavy rain. Does this sound accurate to anyone?
