Welcome, here on the forum, jot your needs down, and start reading, for me it was a wild process that went from 25' used to new to 19' used in space of a week or so. I was so obsessed it was ridiculous
. What I have sinced learned, there r plenty of Airstreams,new and used and to sit back and really decide exactly how It will be used. In my case I travel about 160 nights a year alone using it for work, Bambi is perfect, just enough space. For times my husband joins me as a vacation, still just right. For times grandkids come, still fine for now. Perhaps down the line we will go longer but no need to for now.

For some perfection takes a little longer...
