it would help if you listed what hybrid your have.
some have three bunk ends, some have two bunk ends and some have only one bunk end.
does yours have ducted a/c?
are you using Popup Gizmos or the generic solar blanket versions?
are you using Reflectix in the windows?
this subject is discussed constantly on the Hybrid Forum and a quick search will provide tons of info, without having to wait for responses.
