We downsized from a 32 foot Winnebago Class C to a 23 foot Airstream trailer. We are pleased. Each one has advantages and disadvantages. You have to decide which advantages and disadvantages are important to you.
When we had the motorhome, my bladder could go from gas up to gas up so I didn't have to stop for a potty break. SWMBO could go while we drove down the road. As I aged, my bladder got weaker so I was having to stop before a gas break. That particular advantage went away.
We like not having an extra vehicle to maintain and insure. We had a vehicle JUST to tow behind the motorhome. Now, we only have our two daily drivers, and mine is the tow vehicle.
