I grew up with a TC. When I decided to get an RV, that was my first choice.
Due to cost, I ended up starting with a small TT. It was fine for a few years, but wasn't really great for my style of traditional camping.
I ended up getting a 21ft class C. That has been much better. It gives me more room than the TC (they seemed a lot bigger when I was little), gave me a dry bath, and I didn't need to upgrade my daily driver to a large pickup.
Similar to the TC, I can fit into pretty much all my favorite camping sites. I'm not an RVer and don't stay at RV parks or do extensive city traveling. I tend to go into forests and camp in small to mid-size campgrounds. The 21ft C works great for that - easy to get along the roads and big enough to be comfortable.
I would look at your preferred travel/camping style and really think how a 30ft rig would affect that. For some, it makes no difference; for others, it would eliminate 75 percent or more of their favorites places.
