Wow that sucks, I’ve only had positive experience with CVT. Granted I don’t even trust mechanics to change my oil and I do all my own maintenance, repairs, and upgrades myself so I installed both RTTs myself. We broke one buckle on our Rainier and CVT promptly sent out a replacement.
What tent do you have that requires removal of the rain fly? Removing the fly would be a major PIA! We leave ours on all the time and have had zero issues with water.
I have the Denali Summit Extended Stargazer. What I learned, however, is that contrary to what I was told by the guys making things up as they went on the demo, I am NOT supposed to remove the rainfly when folding up the tent...
