We use hinges like the one in you picture in the control surfaces of our model airplanes, only of course, a lot smaller. They work good, until they break. The thing that gets them is sunlight. It makes the plastic brittle and then they break. I know it looks like a good idea, but personally I would be afraid of it in an application that would get a lot of sunlight like on top of a teardrop trailer. Just my opinion.
I definitely respect your opinion Steve as a TD builder and model airplane affectionado. But...
I already bought the damn plastic hinge, so I submit the following research I did before I bought it. (besides Shil saying it worked for him)
Polyolefin elastomers (or POEs) are a relatively new class of polymers that emerged with recent advances in metallocene polymerisation catalysts. Polyolefin elastomers have emerged as a leading material for automotive exterior and interior applications. Saturated polymers provide excellent thermal stability and UV resistance. POE's provide superior elasticity, toughness and low temperature ductility.

With that being presented, I know not what material your smaller plastic hinges were made of but it might possibly have been pre-POE era plastic. I think this thread deserves to be revisited in a year or so and see how these POE hinges are holding up... I know I will have a personal interest in the subject, as will Shil. So, I will use the hinge I have, but keeping what you had to say in mind, will install it in a way it can be removed without too much deconstruction. Thanks for the input.
