Let's face it, this question can never be answered because we all use our RVs differently. Some people drive to the local lake, set up camp, drink beer and don't move for a week. I tend to tour and visit a great many scenic areas on each trip. I rarely camp in the same place more than a few days and even then I typically drive at least a few miles every day. Other days it might be a few hundred miles. I tend to travel for many weeks or a few months and average 15,000 miles of driving. I live on the East coast and prefer the Western scenery. Driving a lot means I appreciate a smallish, lighter weight rig. I TC gives me a good compromise. Some people really want their comforts and a great many TCs are really big and really, really heavy. Personally if that is what I wanted, I would switch from a TC to a trailer or 5th wheeler.
