I have had both a TCer and a Class C. Loved both of them, the TCer was a lot better to go off road (not the crazy stuff just the lesser traveled places). Big draw back was that it was smaller/ less storage and the going from front to back. Love the class C but even with it being the same length of the TCer it is wider and I have issues on some roads that I travel, not the usual roadways but the side routes and areas that I shoot in.
If you can try renting for a week, while it may not tell you everything it will sure help. Also, go used and buy something basic and if it works out upgrade. You may think you know what you want today but after a year or two your needs may change.
