Moving up from a pop-up

We are moving from a Starcraft pop-up to something new. The TM looks interesting, but I am concerned about reliability. I have seen a number of comments about leaks and water heater issues. Sounds like the lift mechanism has a lifetime warranty, so it must be pretty reliable. What about other things that usually break. I am sure things break and need to be fixed, but I am wondering how often and how big the issues are on this product. They are pretty expensive compared to smaller TTs so is it worth the extra expense?
