I like having options and my RTT is one of many options for accommodations for the evening. I will be leading a trip in October over 100 miles of dirt with 2 different camp locations. This is where the RTT excels.
I tried using the RTT as a base camp one time. It was a pain to take down and set up each day. More than likely I won't be using the RTT as a base camp again.
Adding to Kurt's great thread of pros and cons. Top of the list of cons for me: No matter how much you invest....It is still just a tent. Whether it is on a trailer or on a vehicle, wind can make a night unsleepable. In a large gathering with close neighbors like Overland Expo or Rendezvous, late night noisy neighbors can be a problem. Also a con; When mounted on a vehicle is the suspension of the vehicle exaggerates minor body movements.
