I, for one, like small. My little 20 foot TT does everything I need it to do.
I've slept 6 adults in my 20 foot during a rainy night and we were comfortable. I've had 4 adults and 3 children in it once.
If I'm out camping I don't need to bring my whole house with me. A place to sleep, and a bathroom, is all I really need. I like having a fridge, a sink, and a cooktop (for rainy days) too.
It all depends on the type of camping you do and the type of people you are.
Have a nice Day.
P.S. I hope the PM message I sent you was not a scary one. lol I apologize if it was.
