Thanks for the comments on the fiberglass 'egg' tiny trailers - Casita, Burro, Scamp, are there other major brands? I learned checking for wood rot would be important if buying one used.
We tent camped on the ground until infants, then if bad weather was forecast we would still go, but used a tent trailer.

Now older, a small enclosed trailer looks mighty inviting.
