I was considering adding an 8'6” wide single axle in the rear of the trailer.

For the moment however, my question was at first about the hypothetical 8' wide version trailer on top of a 7' wide trailer, and what safety or other concerns I should be worried about. Stability was foremost in my mind.
Personally, I think you'd have to really make this trailer top heavy for a 6" outboard wall to send it rolling from a curve in the road or a wind blast (that your TV can handle).
I didn't want to clutter up my first post with design stuff, but maybe it will help. The Big Plan is to braze a somewhat minimalist frame of aluminum tubing, glue 1" thick foam boards to each other on either side, then do pmf on the resulting 2" thick walls and floor. What I'm going for seems sufficiently longer than most of the teardrops I've seen here to warrant some kind of framing, even if it's relatively light. As a side bennie, I think it will help with access, like putting in chases.
My next build will be 12'-6" long and will incorporate some framing. So, ya, think you'll want some as well. I'm looking at steel studs like we used for interior commercial framing. I'm thinking framing the narrow way (1.5" thick), infilling foam, then a layer from on a side and 1/4" plywood on the other.
I'm flying without a net here, with little experience and even less advice, and I understand how that will yield things that sound loony or laughable. I've had that from most people I've talked to about this, even on the basic points. Like building something called a foamie. That's why I've come here, and I'm really grateful to you for teaching what you have already.
Hear ya on that one! Once I mention foam.. an eyebrow raises!![]()
I'll take some time to sketch things up a bit. Maybe my questions will be a little more informed that way!
