I've been in your shoes before with a different tt and I really do understand.
We are lucky to have RV Guy on this forum and because of that many of us post our problems hoping that he will have an answer. That sure makes it seem like the majority of us have multiple, ongoing problems which is far from the truth.
Unfortunately you and LKicklight seem to have "above normal problems". I got that term from my last manufacturers warranty guy. At least that's how he referred to my problems with that particular tt. Most of what you have posted should never happen. It's inexcusable.
I'm not trying to change how you feel about your PT unit. I'm not having to live with your problems. I'm just trying to let you know that I do understand that it can be very frustrating.
I do read the post where people write about their problems with their PT units, but at least to me the biggest majority of problems I read seem to be common with just about any new RV.
So why do I believe in PT?
First the obvious. They stand behind their product. 100%.
Second, because of their manufacturing materials and process. They might be only small differences than what others do, but to me those small differences are enough. I'm not going to list what they do here. There's alot of information on their web site and RV Guy has has already posted about many of their manufaturing materials and processes on this forum.
I realize what I think doesn't mean much to you, but please believe I'm wishing the best for you. I hope that soon your Crusader will finally have all the bugs worked out and you can camp without any worries and enjoy the time with your family.
