since they are the #1 mod for hybrid trailers, i guess i'd have to say YES!
you can do a search on any of the 6 hybrid forums i belong to and you'd find thousands of posts about how great they are.
they provide temperature regulation in cold and hot weather, they help reduce inside condensation, they darken the tent ends for late risers and naps and they help keep the canvas protected from tree sap and bird poop.
is that enough?
by the way, i've had them for over 7 years on my hybrid and i always use them.
