1980? Trillium Jubilee Reno

So I have just acquired a Trillium Jubilee that needs lots of love. I have fairly limited building/construction/renovation experience, but I figure the best way to learn is by doing!

Here are the bare bones as they exist right now.

The floor is rotting and still wet. I'm thinking that there is water under the sub-floor. So, I assume that the floor needs to go. And with it I think all the cabinetry, it is damaged too.

Here are a couple of shots of the wet wood and water damage.

Just inside the door I ripped up a chunk of the floor to see underneath.

Can I just start ripping it out, is it that straightforward? I would keep the cabinet intact wherever possible as a reference for replacement.

Once all the sub-floor is up, can I walk on the bare fibreglass bottom? Should I lay down a plank of wood to act as a balance beam/catwalk?

Also, there is a metal beam that runs across the ceiling towards the front of the trailer. Is this standard for a Trillium Jubilee? Or is it something that was installed to fix some yet unseen problem?

One last question for today. Dealing with the insulation. I assume it all needs to come out incase there is water trapped/travelling behind it.

It is peeling off in some spots.

In other spots there are chunks missing and it has been painted over.

Once it's out (if that is the right way to go), do I need to replace it? Does anyone just paint the fibreglass shell and go insulation free? If not, where does one get the insulation, know what to get, and how do you get the funky white bumpy coating over it all?!?

Thanks so much for your help, in advance. I wanted to seek some advice before I did anything. Can't undo a demolition...

That foam insulation looks different than the one in my 5500.
The usual Ensolite insulation (I assume that's what I have, I never compared with any other Trillium) is about 1/4" thick, black, closed cell foam, coated with an off-white vinyl.
The type of insulation in your pictures looks like a thicker yellow open cell foam (holds water like a sponge) and covered with a textured vinyl that I call "popcorn" finish. I did found some of that stuff inside my 5500, along the belley band, behind the actual Ensolite. I was about 1/2" thick. I figured it was there to fill the recess inside the trailer where the belly band is, to make the interior wall even. Under the windows, the stuff was wet and full of mold. Also, that foam looked much more fragile than Ensolite, looked much easier to tear off and rip apart. Is the entire interior of your camper insulated with this?

I have not done extensive floor repairs in mine, but I know the fiberglass shell is rather thin, and I would not walk on it without a proper plywood load spreader over the trailer's frame.

I'm not sure how the interior of the Jubilee is, but before demolishing cabinets, be aware that quite often the cabinets are part of the trailer's structure, and are used to support or brace the fiberglass shell / roof. I would have at least temporary braces ready to put in place if required. Also, note how and where the cabinets are attached to the shell, in mine the cabinets are screwed in glassed-in wood backers and/or the wood of the window frames. Keep the old cabinets to use as a template to rebuilt new ones if that's your plan.

You will need to re-insulate the walls with something or condensation will collect on all the walls... In winter when its cold outside and you have heat inside the walls will fog up like glass and water will run down the walls....

We are only planning on using the camper in the summer, maybe the odd time in the fall/spring. Will it make a big difference in the shoulder seasons? I'm open to anything at this point!

So I spent my time tonight alternating between scouring these forms, and watching the broadcast of the final Tragically Hip concert ().

I think I have decided to reinstall the insulation. I'll use ensolite and paint it. Any thoughts on how to support the fibreglass shell during a gut job? Jack posts are expensive. Could 2x4s cut to fit do the job just as well?

Any other thoughts would be welcome!

Absolutely. Just wedge a few 2x4 of the appropriate length where needed and put a piece of plywood (or the cut off part of the 2x4 to form a T) against the ceiling to spread the load. The shell is very light, this is just to prevent it from sagging, actually 2x3 would be more than strong enough.

I'm no Trillium insulation specialist, but one reason Ensolite is used is it can be stretched to fit the rounded shape of the FG shell. The Jubilee being squarer, there might me other alternatives to Ensolite. Some have used Reflectix ("aluminium buble wrap" that you can get at most hardware store). Now I'm not sure how better or worst it compares to Ensolite as an insulation material, cost, availability, how it is glued, what type of finish to put over it, etc, but I'm sure if you search the forum you'll find a lot of info on it.

Did a complete gut also!

Fortunately I have a wonderful person doing the work for me. The FG floor was wearing away so that was reinforced and then Drycore was put down as sub-floor to keep dry. Oh... I should mention all the little holes (numerous) were patched. Put new flexible insulation in and then rebuilding. Remember to use non-rusting screws. Mine was ready to fly off the trailer...very scary.

Good luck with yours. And have fun!

Wishing you all the best, and breathing a huge sigh of relief that we finished our 1973 amerigo July 3 this year. I wouldn't go through all that again for anything.

I'd rather fly...and I refuse to ever fly again.

But when it's done, it is SO YOURS!

Again, best luck, happy fixing, speedy work, and eventually, good camping!

(Kathleen & Paul near Renton, which is near Seattle)
(Our threads about "fear of fiberglassing" and "73 amerigo) show many photos of our huge mess and work

Showing the 2x4 brace to push the ceiling up before installing the floor-to-ceiling walls and galley -- Paul used a piece of plywood top AND bottom to give it lots of widespread support, and made the 2x4 a bit long, then tapped it very slowly into place with a rubber mallet. Even in the amerigo, which has a fairly sturdy roof/ceiling, it made a visible, measurable difference to support it.

Thanks for the suggestions and pictures of the supports. I bought 2x3 studs, they were on sale! But I'm not ready for them yet. Today was all about starting to pull back the foam insulation and starting to rip up the floor.

First the foam. It's definitely an open-cell foam. Looks like a big, thin sponge. I don't know when it was applied, or why the choice was made.

You can see it here:

When I removed the fridge, there was no insulation behind it. Also the cabinet that holds the fridge didn't go all the way back to meet the fiberglass shell. I'm assuming that is wrong - right?!? Shouldn't the backside of the cabinets meet the shell? Can someone let me know if I'm right on this one?

Notice the gap between the cabinet and the wall, the lack of insulation, and the black mould on the edge of the foam.

Also the gap on the other side of the fridge cabinet. Also no insulation and a random bead of caulking.

This is a piece that runs across the upper part of the wall, above the window and then under the shelf above the dining area. I'm not sure how it is attached, and what it is attached to. I want to take it off, the foam is behind it. Is removing this strip a bad idea?

And then the floor. It was so rotten in some places that it was disintegrating as I removed it.

I'm not sure how the subfloor was attached. In some parts it popped right up, and in others it has almost become part of the frame. You can see in this picture the wood fibers that are imbedded in the resin (?) or whatever was used to attach it. At the bottom of the photo you can see the edge of the dried adhesive and the fibreglass shell. How do I deal with this?

In amongst the shards of rotten floor and super resin I found a bolt and two screws. Any ideas what these would be for?

I assume this is the bolt that attaches the body to the frame. Does it have to go through the new flooring?

These are two random screws that are coming up from the underside of the shell. Not sure why they are there for. Was thinking I would just slice them off and pretend they were never there. Thoughts?
