I have a 35 foot long Royal Spartanette Tandem Axle Aluminum Travel Traier for sale. I think it's a 1951 model, anyway. It was built by the Spartan Aircraft Company in Tulsa, Oklahoma. I will be posting here as I learn more about it, in hopes that someone interested in buying it, owning it and restoring it will give me a call and we can work that out. My contact information is at the end of this page.
Here is a movie I made. This is the exact unit that is for sale:

Today I got some seriously useful help from these guys:

They say it might be a 1952 or a 1953 based on the steel trim on the outside. Apparently the earlier ones used aluminum trim.
