Help! Interior cracks in fiberglass

Hi Everyone- hoping someone can help me! Spent the last summer finding and putting an extreme amount of hours into redoing the interior and exterior of a 13ft 73’ Trillium. Just uncovered it for the spring time and went in to do a cleanup and found two big 3-4inch cracks in the fiberglass between the dinette benches and the “sink” cupboard and tall cupboard(basically along the seems headed downward on both sides of each bench). It terrifies me because I automatically think “is the trailer cracking in half!? Because these cracks are on a seam am I able to do a fiberglass fix? Or will the cracks just continue to grow anyway?! I stick my head in the cupboard under the sink and see light through...and it looks as if it might of been patched from the inside before as there’s left over fiberglass that’s come loose...or so it appears and at the back of the sink as well at same spot. I never seen these gigantic cracks before on the visable side. Looked in backside of tall cupboard but can’t really see corner as box panel is there. If anyone has some insight it would be greatly appreciated.
I’ve attached a pic (not of my camper because I forgot to take some but can attach some tomorrow!) but just shows where the big cracks are forming on each side of the benches.
Thank you everyone in advance!

I recognize that picture because its my camper. On Trilliums, the dinette benches and the sink cabinet are fiberglass pieces that are NOT the shell of the camper. They are molded fiberglass pieces attached to the shell. So if one of these interior cabinets has a crack in the fiberglass, you need to fix it like any fiberglass crack. Either read up on doing your own fiberglass repairs, or hire a boat repair person to do it for you.

Thank you Thrifty Bill- and thank you for letting me use your picture I guess! Lol looks like you know what you’re doing. So I suppose then just patching the crack with fiberglass will be fine and the crack will not continue to grow? I will attach a picture OF MY OWN camper tomorrow so will show size and degree of how it is cracking. Wondering why this happened so suddenly and what would cause it on both sides. Thanks again!

Go under the trailer and do an inspection to see if anything is happening to the frame or the structure. It looks to be right where the level of the flooring changes in height. I would say that there is obviously some underlying shift happening in the structure of the trailer if you are seeing new cracks suddenly developing on both sides of that same area.

Okay! Thank you K Corbin. I will see if we get it up to get a good look under it. Hoping it’s nothing on the exterior shell.

Good point. Its not really the cracks, its all about what caused them. What have you done to the trailer so far? Body to frame bolts? Frame itself? Axle? Floor integrity?

Are cracks a new thing, or just something you recently noticed? The dinette side to side is one piece of fiberglass, that connects to the lower kitchen cabinet on one side and the closet on the other. If it is a recent problem, its almost like the rear of the trailer is flexing up and down. If so, a fiberglass repair will only be temporary.

How is the flooring inside the dinette benches? I've seen some Trilliums with serious floor rot in that area.

Yes good point. A weakness in the Trillium frame design is that the frame rails are NOT one piece. There is a splice in the frame rail in the same location where the axle is welded to the frame rail.

When my Trillium 45000 axle was replaced, the mechanic did two things:

1. Added the Dexter adapter plate so that the new axle could be bolted on instead of welded on.
2. Added a large, sturdy custom machined steel plate to reinforce the frame rail splice on both sides of the trailer frame.

Are we talking about an actual crack in the fiberglass, or is there a gap opening up between the dinette benches and the adjacent components? I believe they are separate pieces in the Trillium.

Either way, though , I agree a very careful look at the metal frame is warranted. The most common failure point is further forward where it curves upward, but you’ll want to look at everything. A failure in one place can transfer stresses to another.

Actually Jon, I believe that on the Trillium 1300, the bench and kitchenette are one piece. Trillium 1300 owners can confirm. On the Trillium 4500, the bench and kitchenette are separate pieces.

Pictures!

Thanks everyone for looking into this- it’s very concerning Here are a couple pictures of the cracks. And on the inside of the cupboard as well. I think it is all one unit: the bench and the kitchen or so it looks to be. We have a Tril 1300. The floor was in good shape so I thought! I will attach some pictures of it in the redo mode as well. Before the hardwood floor. And underneath the camper. We did not do anything to the axle or undercarriage besides some black tremclad- we’re fairly new to this game and all looked fairly decent under there but opinions on anything alarming would be appreciated!

More pics...

Looking underneath along where the floor height changes...I’m not seeing any cracks or anything even where it meets the axel... here’s some pics of both sides by wheels

Pics Before redo...and after

So I’m trying to look back and of course cannot find a pic of area where cracks are- but I would think I would of noticed them painting and whatnot....so maybe they were very tiny and grew over this last winter? Very hot hot summer last year here in Ontario and a fairly cold winter (as usually lol)- would hot and cold be a factor if stored covered outside?

Thanks John- so basically there’s a spice where we are seeing the cracks located? Am I catching that right? Underneath I’m not seeing any cracks to the shell. Our axle is a bit rusty but not sure how to know if it needs replacing or if there’s a bad shift where you say this splice is? How can I tell?
