I also love the road trip part, broken up with some activities around brief base camps, but the base camp days might are sort of mini road trips since I am toadless and even a couple of miles to a trailhead means leaving camp in the RV.
My Tiger is just under 20 feet long, an excellent road trip (and off-road trip) vehicle.
RVers have different preferences. For some folks, I suppose they don't really know what they want because they are just starting out and they have to buy what is available or what their friends have or whatever. I've been camping in small TTs and small Cs since the 1950's and this style of camping and travel is where I belong.
Isn't it great that there is a place for all of us here at RV.net!
