JMHO from camping and RVing for over 60 years. During my working years of weekend get aways and short vacations and not much parking at my home it was convenient to be in small units like TCs or similar types. easily parked at my home, no distant storage required. Most weekend trips were quick spur of the moment get aways with out much planning and usually in the summer months. Smaller units could go just about anywhere. Now much older with long vacations and not too inspired with camping in hidden forest campgrounds or treking down logging roads larger units are a lot more comfy. Big RVs are highway machines. We still do some limited off road camping with our class A but not the fun of treking down logging roads to see where they go and camping far away from other campers.
