To answer the OP's question, we went from a 25' TT and back to a truck camper once our kids were no longer interested (and they had their driver's licenses)
I was amazed at the amount of stuff that we emptied out of all the TT's storage areas, cabinets and closets.
I think we put about 20% of all that into the TC and didn't miss the rest.
We tend to move from place to place, using campgrounds for nighttime stopping places. Even if we are in one campground for several days, we will drive around with the TC so our kitchen and bathroom comes with us.
The mobility that you gain with a TC versus a 5th or TT is really great.
