I'm all in favor of choosing the RV/traveling domicile that suits your current needs. It is beyond form-follows-function. Example: This past July we camped the Oregon Coast with all our kids and grandkids. What a great time. Jeanie and I were in our TC with one or other of the g-kids for sleeping. Our kids rented a 26' Class C for the 8 days we were out, so we traveled in two vehicles and arrived at our daily destination(s) and hooked up.
Any time you get more than two breathing beings in our TC it is instantly too many occupants. The C had marginal sleeping space for 5 (including the family dog) and it was slightly more roomy with the 'token' slide-out, which was good for playing games at the table with the kids in the evenings. It cost about $2000 to rent and use (fuel) the C for the duration. Did it supply our needs? Yes. The Ford V10, series 4 chassis got 11 mpg, which surprised me since we only got 13 mpg with a much smaller rig. It seemed much easier to actually be somewhere in the C than to travel with it, compare to the TC which wants to keep moving (because it's easy).
A couple months ago I saw a 26' class C for sale: (Ford 5 series chassis, dualie, diesel, 4WD, good ground clearance) and had terrible thoughts of bolting from the TC den into C-dom, but thought better of it since all my stuff is paid for...and we're used to it.
