Bikendan,
We had a 21SSO as well and changed to a hard sided trailer just about the time I retired. I loved the hybrid and will not speak ill of them. But, like all things, things change and so do our needs.
Welcome to Washington. It is a great state to go camping. It has an amazing diversity from rain forests to deserts, ocean beaches to sand dunes, farmlands to deep forests, rolling hills of wheat to mountains with lots of lakes. There are many campgrounds of the National, State and County variety as well as many places to camp free of charge. I just drove through Texas where 97% of the land is privately owned. Camping, hunting and fishing up here is a little more accessible to the common family.
