Trillium 1300 Frame Question

Quick question: Does the original frame on a '78 1300 contain any wood "beams"?

When I bought this, both my husband and I got down and looked underneath the trailer to check for the obvious. Neither of us actually slid under there for close inspection, unfortunately. I did yesterday for the first time and noticed two wood beams running the width from around the door area across. They were dark and looked like the metal until I actually scratched at one.

This may just be the straw that breaks the camel's back. I've had it with unpleasant surprises!

Oooo, I've never heard of that, only metal. But let's wait till some other people with more knowledge of trillium frames come along, it's a long shot but maybe someone will say it was unique to that year!

By 1978, the frames were done changing. There may have been some small changes, but wood was never part of the design.

Ruth, please post pictures. The wood members, (especially how they attach to the frame) the tongue, (from a low angle) and the axle are what I am interested in.

One of my Trillium 4500's had some questionable welds on the cross members. Maybe some of yours rusted off, and were replaced with wood. Believe it or not, this would not be too difficult to fix. The body comes off the frame with six bolts, and removing the propane connections. Welding on C channel cross members is not a big job.

I'd really like to see pictures of the trailer underside/frame if you can take some.

That way we might be able to tell if the wood is meant to replace original steel cross braces, or installed for some other purpose....or even whether it's the original frame at all!

My 1878 Trillium 1300 frame is all metal, no wood beams.

This is how it looked before I modified it extensively, I had already removed the propane shelf on the front. A PO had added the rack on the back.

How many "horsepower" was the tow?

Oops!

Must have been one of those Conestoga 1300 Trillium Wagons. The TV was 4 "horsepower"!

That's what I get for having fat fingers.

Frame Pictures

Thanks for the input, all. Spanke, just seeing that beautiful frame and knowing it's your "before" picture makes me think mine just needs replacing. One thing I've realized: Now I know why the floor felt so solid inside. With two beams right there, how could it seem soft?

I meant to post pictures but have to read the instructions first since I don't have pictures on a URL. What's up with that?

Ruth,

Structurally my frame was in good shape. Replaced the axle with added brakes, rear jacks, front coupler to fit 2" ball and front jack, modified the spare tire holder and propane/battery shelf, added breakaway brake switch and painted it with por15.

Here's an "after" pic.

Ruth to post a photo click on the Paper clip and you will get a pop up that allows you to select a photo off your computer & upload. If you click on the little world icon on it with the link you get asked for a url.

A couple of observations:
- Your frame is an original Trillium frame.
- Those wood beams have been there for a while.
- They have been installed in a way that will not compromise the strength of the frame.
- Your frame has plates welded on either side of the frame rails where the frame goes under the front, as it should.
- There is an extra square tube running from the coupler to one of the cross members. It looks like this was done to support the propane tank shelf. Way over kill.
- Your axle looks like it is sagging a bit. Not too bad.
- Your frame looks like it is in good shape, rust wise.
- You have the plates for brakes, but you don't have brakes.
- The wood beams do not seem to be replacing anything. They are installed where there was nothing. See attached drawing of my Trillium 4500 frame. I did not see the first cross member. It should be just before the frame reaches it's full width, in the front.
- The floor of my trailer feels firm with no cross members at all where yours has wood beams. I wonder if this was to deal with rot in the plywood floor. What do you have on the floor on the inside?

All in all, I don't think that this is a sign of any major problem. Just a previous owners over engineering.
