We tried out the bed last night and both fit -- it was cozy but do-able. Our schnauzer, Duncan, will have his nose out of joint because he is actually going to have to sleep on the floor for once.
I have a Surfside TR 14. One of the nice features is that it has the capacity for a [b]small, full, queen or king bed (really!). I don't know why manufacturers today don't adopt that style as an option.
That sounds like a Casita Liberty to me. Yours is unique in that it is available in a 14' long trailer, shorter than the Casita.
