Finally!! My very own truck!

If I understand correctly you have a used car lot and just "borrow" a truck to use for camping? I presume running dealer tags on it while camping? From what I know from my family in the business it's not legal to use dealer tags for that purpose. There for moving vehicles around between lots, test drives, and service. Test drives don't include hauling a camper.
I'm happy you get to go camping but, coming from someone pays all the legal obligations of vehicle ownership:taxes, tags, and insurance on my truck, I don't have a lot of sympathy for your situation.
