Just realize the beds are "twins" in name only. They are much narrower than a standard twin bed. And the center aisle is very, very, narrow. We had a Liberty (like the Independence, but the twins were even narrower). But it could also be set up as a king bed. Anyway, we hated it. We learned we would rather have a smaller bed, but a separate dedicated dinette, than a bigger bed.
As far as what to add on, a furnace
is optional, not included. Well, in TX a furnace
is not so important but where I live, its a must.
And to be fair, many people love their Casita
. If I bought one now, it would either be the Spirit or the Freedom.
One challenge with most molded FG trailers is they are narrower than traditional "stick built" trailers. A traditional trailer might be 8 feet wide, whereas many of the molded trailers are about 6-4 or so wide. So fitting two twin beds across from each other just doesn't work, as a standard twin is 39 inches. OR 78 inches for two. Thats wider than the trailer. So they put in narrower beds and call them twins.
