Hi, I'm one of those with five Trilliums, (down from six). Your frame is rough.
Also, the
furnace does not look original. Another observation, it looks like a previous owner put in a stove vent.
I think all the 1300's have a kitchen counter that slopes towards the wall. The 4500's less so.
It would appear that your frame rusted out right where the bolts would have gone through it. Putting holes in the frame was something that Trillium eventually stopped doing. As mentioned previously, they welded small angle iron stubs to the frame and drilled through those instead. Also they welded fish plates at the bend. Being nearly center, between the coupler and the
axle, that is a high stress point. I have done some drawings of a 4500 frame. See attached. These were posted in this thread:

There are five items to check on all Trilliums:
1) The
axle. Yours is probably not worth saving. If it is the original, then it's 43 years old. They age. After several years the rubber gets very hard and the axle no longer has any travel, or the rubber disintegrates and the axle sags. Get a new one, with
brakes.
2) The door. The quick and dirty fix for door sag is to pull the door off, but leave the hinges attached to the door. Fill the screw holes with resin, and glass, tape the door back in place and use the holes on the hinges to drill new mounting holes. This is at best a temporary fix. This thread shows the best fix I have yet seen:

3) The belly band. I see that the belly band has fallen off your 75. This is a complex repair:

4) The frame bolts. They always rust out. Some disintegrate completely.
5) The
windows. The butyl tape gets old and the seal is compromised. You pull the
windows and install new butyl tape. This is actually kind of easy, unless you also have to replace the plywood frames on the inside:

Clearly, you have some work ahead of you. But it is worth it. The resale value of these trailers is quite high, and they are very practical.
Please take a minute to confirm the manufacture dates of your trailers. I see that your 73 has a serial number / manufacture date sticker on the front, just above the red sticker. You can also compare the serial number of your 75 to this list:

Please feel free to post your serial numbers, so I can add your trailers to the list. The sticker on your 73 is of great interest. That is a good way to calibrate the list.
