We are currently on our 5th truck camper. Bought the first one in about 1974 but seldom in the years since, has a TC been our only RV. Some of the years we also owned a Class C, bunk model, then a couple of Class As, and now a 5th wheel. For us, we haven't found any one type of RV that handles all our needs, especially now that our young, 9 and 11 Y/O grandsons go with us more and more. The 5th wheel is our choice when we are going to be parked for a week or so, if just the wife and me, we tend to take the TC. We use the same truck for both. Some doubling up of costs, insurance, etc. but it is worth it to us at this stage of our RVing life.
We did take the TC last summer, with the grandsons on a 2 1/2 month tour of the mountain west. Mainly because we wanted to drag our Jeep out to western Colorado to run the mountain trails. Four people and a beagle in a non slide Lance 845 did get a bit close at times but we lucked out on weather, most to the trip, and could be outside except for sleeping most days.
