Determining VIN or Serial number on 1968 Travel Queen Camper

I unfortunately can't help with your question, but I'm wondering if it accidentally posted in the wrong forum. Are you talking about a travel trailer that you tow behind another vehicle? Or are you asking about a truck camper that slides into the bed of a truck?

If it's a truck camper you might want to ask a moderator to move your question to the truck campers forum. The truck camper group is definitely active and you should get you answer.

Good luck with getting an answer and welcome to the forums.
