Mark, you have quite an amazing Trillium. In 1973 Trillium did not offer a front dinette. The one in your trailer must have been installed by the PO. It almost looks like they removed the fibreglass from another Trillium and installed it in yours. Are there any structures inside the seats that would indicate it was handmade? They hung the table from the window frame, avoiding putting any unnecessary holes in the shell. This is what Trillium did as well, but with a fibreglass back splash that went down to the seats.
I have some comments about your
furnace as well. I am a big fan of “gravity” furnaces. That is, no fan, or
electrical requirements. It is totally gas powered. This particular model has enough space around the gas valve to be able to change it, without needing to pull the
furnace. This is important, because frequently the telescoping exhaust/intake assembly will have fused due to rust. It is probably not possible to remove it now, without destroying it. This furnace has very few things to go wrong. The thermocouple may need to be changed, or the pilot
light may need attention. The killer is when the gas valve quits. Newer versions of the Duo-Therm furnaces don’t have enough room around the gas valve to spin it. This makes it very difficult to change the valve. The condition of the furnace grate is also worth mentioning. I have one of those grates which is missing about 25% of the louvers on the front. The design is kind of flimsy. Your looks perfect.
Is that a 12VDC electric
fridge? What I really like about it is that it doesn’t mess up the road side Trillium logo, like a
propane fridge would, another very rare feature. Tom Young was selling chrome like stickers that fit the logo, minus the stem on the logo. Trillium eventually dropped the stem. One on either side would look nice.
If this was my trailer, there are only three things I would consider changing. One is the
tail lights. The ones on you trailer are after market, (Princes Auto? LED?). You can get the original Bargman
lights from Paul Neumeister:
Fibreglass RV Parts, Repairs, and Service by Paul Neumeister. If your existing
tail lights are LED, it would be worthwhile to remove the guts and put them in the Bargman
lights from Paul.

The second thing I would add is a 14” powered vent fan. I like the MaxxAir 5301, (four speed, manual open):

The optioinal motor to open and close seems redundant; since the fan is designed operate when it is raining. This is not a small job on a trailer with a 9” vent. The hole has to be cut larger to make it fit. I would also recommend some pultruded square tube to frame in the hole from the outside. This allows the fan, and its controls to be flush with the celling, or a bit recessed, depending on the size of the square tube:

Lastly, I would consider enough
solar, (either on the roof, or as a suitcase) to run the fridge.
Boy, am I ever wordy.
