I am not sure if I understand your question. I have a 07 Eagle 325BHS with the thermal windows but they are not tinted. I find my unit is a lot quieter and warmer in cooler weather than my old 5th wheel because of the windows. It would probably be a lot cooler if my windows were tinted.
I would think that it would be a nice option. If you think about how long you will have the trailer and the advantages the up graded windows offer it is a minimal amount over time.
Especially as you stated you have all the other options. I'm sure you will be glad you choose the option.
Congrats on your new order and welcome to the Jayco Owners Forum Gibby!
