We have all thermos on our Heartland for 5 years now. They ate still new. We have over 30k miles on the unit and driven the worst roads in america. In New Brunswick Canada that is.
I only heard of Motor Homes windows that have failed.
But. I am not sure the frames on TTs are stiff enough, have no experience, just my unit.
They sure have been a blessing with the last 3 cold southern winters.
Beats having to cover the windows with blankets to heat the unit and running condensation every day.
