Conclusion made: 95% of all TT's are a crapshoot

Buy what you want and the first thing to do when you get home is check the roof and add sealant anywhere you think looks suspect. And repeat this at least once a year.
Fixing RV components is not rocket science but getting water intrusion can destroy any RV brand in a short time. Most new RV owners don't have a clue that the roof needs attention every year. And because of this they get 2 years in and they are complaining on the internet about failures.
