Our 2013 Eagle has thermo windows and the glacier package. What a difference as we use it all winter long. I think the savings in propane will eventually pay for it. also our bedroom window no longer is the coldest part of the trailer.
Love our Jayco and the bad press form the Wyoming guy is just that. We have had warranty issues (not many) on this model and our 2008 all of which were done well and to our satisfaction. I guess the dealers in WY are not up to the level as ours in Michigan!. Oh and when I've had suggestions and issues Jayco has listened and changed the new models to accommodate our ideas.
