Hi again,
I'm glad to see that you are getting used to the forums. It's not uncommon for new owners to get the jitters after buying but figuring why can be important. I had some jitters but mine were money related as I was paying cash plus wondering what I was getting myself into.
My suggestion would be to have the RV inspected. Not sure how much this would cost but the inspection could be worth the investment. Water damage is a key factor to look for especially when there has been signs of it previously.
I do recommend checking the blank tank with a flash light looking down the toilet to see if the previous owner left it emptied or otherwise. It's not uncommon for trade-ins to sit with the black tank dry but not empty which creates a problem later on.
