This restored 1957 Spartan ‘Executive Mansion’ travel trailer is up for auction on eBay right now. (SOLD: Post taken down)
It’s 8′ wide by 50′ long so it’s approximately 400 square feet of space inside with no sleeping lofts.
Finding this trailer really opened my eyes to what else is possible with tiny houses on trailers.
According to the owner/seller on eBay, “After WWII Tulsa Oklahoma’s Spartan Aircraft company switched its production of aircraft to travel trailers, including this spacious and ever so rare park model, the 50′ Executive Mansion.”
It’s technically a park model because it has no holding tanks so it’s designed to be used at a campground, RV park/community, or on your own land.
