Congats on both the Trillium and the baby. Babies change EVERYTHING! Fortunately, your trailer is good for at least two kids. I have five kids, (and six Trilliums). How then can I use a trailer this small? We tow with a Travel van that has a back bench that folds down to a bed. My wife and I sleep in the van. The kids are in the trailer.
There are problems, and then there are PROBLEMS!!!!
I have said, in the past, that there are four major maintenance items, that need to be addressed on a Trillium. But, after reading John in Michigan's posts above, I would have to agree, the bolts are a must to change. The others that need to be looked at are:
The belly band:
Got nothing. Not happy with my last attempt.
After 40 years, yeah, it needs to be replaced. Get one with brakes
BIG PROBLEMS would be rotten wood in the floor. This feels like spongy spots in the floor, or all over the floor. The floor should be quite stiff. Also a sagging front curb side. The door is a rather large structural flaw in the shell. Sometimes the front, curb side sags. This can be seen by standing on the tongue and looking down the curb side flat section of the roof. If the part of the roof over the closet forms an obvious high point, bad. Also, try placing a straight edge, on the floor, with one end near the fridge
door, and the other end towards the trailer door. If the floor appears to sag, towards the door, also bad. If these problem are found on a Trillium that you are looking at, then just walk away.
If I had to guess, (which I do) then based on the Trillium serial number list:
I would guess your trailer is a 1977. It should be noted that there are some rather large gaps in the list, in this area.
I would describe your option package as deluxe. I know that Trillium used that description for the 4500's, but I am not exactly sure that label applies to 1300's. You have the options:
Window in the door
Upper shelves and the associated lights
The only major option missing is a kitchen window. All the 4500's have one.
Curiously, you don't have a porta pottie garage. That is a door in the front of the gaucho, right against the right side near the entry door for the trailer.
What is up with your Ensolite? Bad paint
Also looks like you are missing the back / upper bunk for your gaucho.
