Hey djfrantic
We kinda did the same thing you did....
Our very first rv was a 25SS with the same type of sleeping arrangement you have in the 19....a bed shoved in the corner next to the small bathroom. (hated the bed and the toilet)
After LESS THAN A YEAR we traded for a 27' FB and love it!
With two young boys the 27 gives us a bit more room and storage than the 25'FB.
If I were you I would skip the 23 and go up to the 25FB model...you won't be sorry.
We took a huge loss when we traded for the larger trailer. I don't think there's any way to avoid it...if you really want a bigger trailer you'll just have to bite the bullet and go for it! If only we had found this website before jumping in!
