In the early 1950's, a small teardrop style camper called the Benroy was on the market:
A few photos of restored Benroy trailers:
That's Ben in the photo (you get one guess as to what his business partner's name was
Here's a Benroy plan view I found on the 'net:
Below, I've overlaid a TrailTop on that plan. It's on a Harbor Freight 4x8 frame. The door is a ready-to-install item I found on eBay, so it's different from the original Benroy door. And yes, that's Ben himself. I hope he'd approve
And the original photo I removed Ben from.
One of the points of this post is that there are plans available that one could nicely and easily implement with TrailTop parts. Plans are available for the Benroy, for example, that show details for the rear panty area, and those plans could be used in a TrailTop-based "Benroy" with only minor modifications.
Or, exiting plans could be modified for different uses... next is one a version I've made a bit taller for better headroom and raised the ground clearance a bit from the original low-slung Benroy and given it 31" tires to give it better overlanding/off-road capability.
