mr. Pitney is a nice guy... love the product... we got the super high wind models as well... very well made.
here is how i put ours on... we use heavy duty pinch clamps (those big binder clips work well, also) to hold the PUG in the upper corners, then run the bungees underneath, but the bungees on the end should be pulled back toward the camper... find what works best for you. i will try to take a few photos of our setup next time we are out.
i also bought a roll of the reflective material (the bubble wrap sandwich type), and cut out custom covers for every window in our 19H. also for the sides of the bunks... just unzip one end and slide them in there as well... combine those with the PUGs, and at high noon, our camper is so dark you have to turn on lights to see anything!
it's nice when you've been out surfing or fishing in the bright sun, come into a cool, dark camper...
if you don't have any PUGs for your hybrid, and you live in the south... you really don't know what you are missing...
the PUGs also protect your bunk ends from the sun, bird droppings, sap, etc.
i would stay away from the plain solar blankets... if they get wet, some will release the coating, and you will have a lot of aluminum residue on your canvas/vinyl...
