RV.net has the most active Hybrid forum on the Internet.
there is the Complete Idiot's Guide to RV'ing book, available for most things you would need to know. Amazon sells it.
the only thing different about a hybrid, from other RV's, are the canvas tent ends. other than that, all the other stuff is pretty much the same for nearly all RV's.
#1 mod for Hybrids, are Popup Gizmos or the generic 5x7 solar blankets.
also, many put Reflectix in the tent end windows to help with cooling or heating the canvas ends.
