Congratulations on your purchase.
I bought a Trillium 1300 that was already completely renovated except the lining was coming apart badly in 2 corners.
The buyer took that into consideration when I offered my price.
Nevertheless, I bought it and did some serious
boondocking all winter with it.
It pulled like a gem and served me well.
About yours, it's a great special edition model with the front dinette.
It appears to have all original interior.
It just needs some TLC and you are good to go.
The biggest issue with mine was the lining.
One professional came out and did an assessment on the situation.
So the Trillium is fiberglass, as you know, and although that has it's advantages it's a huge disadvantage when it comes to lining.
As it was explained to me, the molds for the kitchen, the cupboards, and the interior are molded into the fiberglass so fixing lining is a huge undertaking.
It can be patched up, but that won't look good at all.
The professional explained to me that in order to properly fix the lining everything has to come out and be stripped down.
It's a huge an expensive job.
Plus they have discontinued that exact lining although you can buy it on some sites.
So I didn't fix it, and I ended up selling it to a couple who didn't mind doing their own work.
I love my Trillium, was happy for the experience, but I've since bought a 1969 Shasta all original.
I had it stripped down to the frame, completely renovated by a professional and if I had a choice between the two I would take the Shasta any day.
However, like the Trillium the Shasta has its disadvantages.
Simply put, it's made of wood so any small leak causes rotten wood and has to be taken right out to repair it.
In contrast, the Trillium never has that issue because it's fiberglass.
I just found the Shasta to be so much more brighter, with more
windows, and I came to dislike the middle kitchen in the Trillium once I started living in it. I didn't like the layout at all because the kitchen is always "in the way" sort to speak.
With the Shasta it's an end kitchen with a ton of storage.
So it doesn't interfere with the living/bedroom space.
So both had pros and cons.
I never would have been able to compare until I've owned and lived in both.'
All the best with your Trillium.
