EPIC Spartan Royal Mansion 40-Foot Trailer RENOVATION… Originally From 1948!

This post contains affiliate links.

This is an epic 1948 Spartan Royal Mansion 40-foot Travel Trailer RENOVATION. I was contacted by Greg Parham of Rocky Mountain Tiny Homes about it because it was for sale but has now been SOLD! Anyway, it’s still super-awesome, and you should definitely check it out and learn more about it. So, here’s the story on it…

Greg Parham’s brother-in-law bought the old Spartan and hired his super-talented aerospace engineer friend to renovate it and turn it into what it is today. He then used it briefly to live in while building a new home. Now that his residential home is complete, he’s looking to sell this epic and vintage Spartan trailer which served him oh so well. It’s AMAZING, isn’t it?

      Alex – question for you…. how do you create an account on here? I’ve seen people (other than you as the host/owner of this site) post comments with their own pictures or a picture they put up versus the tiny house icon above and to my —>. Not sure if you remember but I’m the 50 years “young” lady so guidance on anything techy is greatly appreciated! Thanks Alex!

      LOL! I was thinking the same thing! I wonder what someone from the Ottoman Empire would think… 😉

    Hard to believe that the whole 40 ft is only on a double axel. That said, if I had $80K I’d grab this.

    Beautiful, classic meets modern. Its not overloaded with stuff requiring high maintenance but has all you need. A kitchen you could cook any meal you like, comfortable living area, did I missed a dining table?, spacious bathroom and nice bedroom.
    Didn’t see any screens and blinds for privacy which should be included in asking price.
    It would be interesting to learn about weight and payload.
    Well done.

    Spartans are my all-time favorites. Would love to have a 1955!

      Compared to the original, yes… But, if you mean like a tiny house, then no… It’s a lot less than you’d see in a typical Tiny House…

    That is gorgeous! I wish I could afford this beauty. So much work has gone into it. I love that the kitchen is in front of the windows where I imagine the original dining area would have been. That would make cooking so much more fun to be able to look at nature while prepping. I was wondering where the second door was until I saw it back in the bedroom. I was pretty certain they always had 2. I like that it is on the other side.
