We own both and enjoy both but as everyone says, for offroad, the TC wins hands down.
Its a completely different way of traveling though and it took a little getting used to, but once we did, we loved always having everything with us. We spent 4 months traveling up to Alaska this summer. The biggest difference is when you are towing, you get to your destination, unhook, set up, then go off exploring. With a TC you get up, eat, go do whatever exploring you want and when you are done for the day, you find a place to park. In Alaska, thats hardly ever in an RV park. SO much easier to boondock with a TC.
We also found we gained time with the TC. For example, if we are staying in a national park and want to do a long hike. In the 5th wheel that usually means staying 2 nights because we would have to check out by noon (or couldn't check IN until 2) and there isn't usually a place to leave the 5th wheel. With the TC we arrive whenever we want, park in the day use, hike, then go to a spot for the night later in the day. Or we spend the night, move to day use in the morning, then hike as long as we want, no pressure. It was a great perk on our summer trip.
