Pete, You're right about the Scamp
with the curved front. ( I have a 16' Scamp also) But my Scamp has the bathroom in the front so only has the very small window.
Andrew, The Horizon is built a little like the Bigfoot
, in that it has about a 1" foam insulation. With a material on the inside. The windows
in it now are about 2" deep, from outside to inside. Now I'm not sure whats behind the material, I'm thinking probably something like luan that they glue the material to. I will know more about that once I take out the fantastic fan, I'm going to replace the butyl putty. I've already talked with a fellow from fantistic and they are just great people to deal with. He told me to send my fan in and they will check it over replace anything needed, at no cost, just shipping. I won't be getting to that until spring when I can get the Horizon out of storage. The window I'm looking at is for a 2" depth, and with a inner trim ring for the inside. I'm not sure how the window fastens to the camper, maybe with the trim ring ?
