Framing layout???

Just some thoughts, that you may have already tried. I will mention anyway.

Are you also doing searches for other model years for the 18' Shasta Stratoflyte ? I see they come in different lengths which doesn't help. Sometimes the search results come up differently if you change the year of the model. Sometimes the models didn't change their interior layouts over a few years.

Here is a 1969 model that is an 18 footer (according to the home page) as an example. ceciliatheshasta.com/1969-shasta-stratoflyte/ This trailer is long sold as the ad was posted back in 2018.

Did you find any models that were for sale? Internet ads generally have interior pix to reference. Youtube has for sale videos that people post. That's another way to find info on interiors, not just a layout diagram.

Just some thoughts.

Most trailers are framed very similarly. You don't have to copy exactly to have a sound trailer. Copy the skins and add backers for fixtures. Of course frame the windows and doors. There should be enough framing left to copy.

You said you were watching Larry's videos. Did you find the series on the 66 Super Shasta? Though a bit older than yours, the build technique in the framing is similar.

There are also blogs with still images, as well. Photos are so much easier to work with than a freeze frame in a video.

This might help when asking questions even though its a canned ham. vintagetrailertalk.freeforums.net/thread/1093/vintage-trailer-framing

When you are planning your framing, of course you start with the placement of the windows and door. Then, consider laying out "studs" horizontally rather than vertically like a house. Running a long 2x3 from front to back will give a lot of needed stability to the coach.
