We went from a 24' FW to an 8' truck camper and it was surprisingly easy. The reason it was easy was our trips had changed.
With the FW we would set up for 10 days at a time in the middle of nowhere and needed the ability to haul 10 days worth of stuff.
With the TC we spent no more than 2 nights in one place and then moved on or headed home. We could resupply easily along the way and didn't need much more than the clothes on our backs, a coffee pot, and a couple of chairs.
A lot of the extras we had in the FW found use in our home and the rest was donated to a young couple that was buying their first trailer. We had the tendency to carry far more than we needed just because we had the room and it wasn't in the way.
Now when we moved from the TC to a 40' TH that was a whole different story:(
