Newbie- we bought a lemon! Delamination issues

Other fun things include me asking if there are any leaks to the salesman 3 times and him saying no leaks. Then found out when trying everything out that the toilet leaks. The water pump leaks and the hot water heater tank doesn't hold any water at all when you try to fill it it just floods the inside of the camper!! I sure am learning a lot. I think I will go to an actual RV dealer next time I want to buy a camper.
