Normally, when a camper reaches the dealership from the factory, the dealership has to "prep" the trailer. When it comes from the manufacturer, the dealer has to do things like, install the propane tanks and battery, anchor things down, adjust things, what-not.
Then, in preparation for the buyer's "walk through," they hook up the electricity, fill the water tank, test all the systems. Then when the buyer arrives, everything is set for a walk through demonstrations.
If you just picked up the camper from the dealer before allowing them to pep it for final sale, then you probably did have many issues afterwards.
I've visited several RV dealerships (one is only 5 miles from my house), and they are getting to know me pretty good there. I have on many occasions looked inside different RV within a day after delivery, and they are usually in pretty good disrepair. The manufacturers depend upon the dealerships to untie, screw, and unscrew, set up tables, adjust, fix and prep practically everything.
Not sure what you experienced, but sounds like you were just too eager to take possession and not allow the system to function as it does.
If you agreed to take possession of the camper from the dealer without any dealer prep as an attempt to save a few dollars on prep-fees and such, then .... there-in is your problem.
