Larry, Last summer several were advertised. This is kinda surprising, considering that they made very few of them. It is my understanding that only 50 or so were built. I don't mean to offend the members who own them, but if you want a bathroom, then you may want to look at other brands. Many 5500's have, umm,... quality issues. They were designed and built when Trillium
was experiencing financial difficulties. It has been said that no two are built the same.
I like the 16 ft scamp
with a front bathroom and a side dinette.
Judging by your avatar, your 1300 has all the bells and whistles, including a kitchen window. Very nice.
I have pondered the idea of cutting out the front gaucho and installing a front bathroom in its place. I was planning to use a 4500 for this, but it should work with a 1300 as well. But the bathroom would be a few inches smaller.
