I purchased a Trillium that has a caved in roof. Sat that way for five years I am told. The rain gutters around the top openings in the dinette and gaucho, and the interior fibreglass floor kept the plywood that is sandwiched between the outside shell, and the inside shell, dry and rot free. Since I had planned to wreck this trailer for parts, I was more surprised by this then anyone.

Trillium has since revised the design of the top openings of the gaucho and dinette seats to remove the gutters. I think this is a mistake.

Further proves the worth of fiberglass as the essential construction model.
Begging Escape to put me on any list to buy a 17B contract that people are canceling. No soap-- too much demand!

There is no fiberglass on the floor except where I added it.

My 92 Scamp has a wood floor that has been covered in a fiberglass resin.

My 10X12 skid shed is made entirely of 7/16 OSB on 2X3 framing. Even the floor is made of the same material. It has shingles on the roof and a single coat of paint applied in 1997 when it was built. It had become unsightly over the years and I hate to paint... so last week I sided it with vinyl siding. I found no rot anywhere in the structure. Many people who eschew the use of OSB in travel trailers may be unaware that the house in which they live is largely made from the stuff.

I agree there is nothing wrong with the use of OSB (my 23 year old Scamp is proof of that) providing the trailers owner is diligent in fixing leaks as they happen rather than waiting months/years for the floor to rot out.

But your house does, and the Oliver is even cheaper and easier to tow!

Scamp floors: In the 70's - mid 80's Scamp used plywood floors. I think in 1984 when scamp started installing the radius windows is about when they switched to OSB. I have seen 1/2" plywood in 70's scamps. In the 80 Scamps I usually see 5/8" floors. A 85 S-19 was the first 3/4" rear floor I encountered. In the 2000> Scamps I see 3/4" floors.
Every Scamp I have seen has had the bottom coated with resin. I don't think Scamp seals the edges drilled holes but I have hot seen any issues from that pratice. Floors rot from leaks from above and more so from neglect not from road spray. This applies to all makes of trailers.

Thanks for that informative post. Even if its not been a problem, I think it might be good insurance to DIY for the cut edges. I'll look at my Scamp when I get it and decide then, but I think I will do some sealing on the cut edges of the holes just for peace of mind.

I just installed a toilet in my Scamp. I sealed the edges of the drain hole with resin. Scamp and I installed a wax ring under the toilet and sometimes a little wax comes out the hole for the black water drain but there is no issue with that. If you have a shower a hole will be cut around the trap. The gray water tank vent loops up under the dinette and back through the floor and that vent line is sealed. The sink drain goes through a fitting in the top of the gray water tank along with a vent line. They come through the floor under the dinette but they are covered on the underside by the tank. The fresh water drain and vent are usually sealed with silicone.

This subject has been covered many times including calling Scamp. The floor is 3/4" OBS the bottom side is coated with resin. The top is painted.

If you watch the Scamp video, toward the end they will show the production. You can see the flooring and watch them putting on the tanks, etc.: Helpful Videos - Scamp Trailers

OSB has the advantage that it is cheaper than plywood. It is also much heavier. Maybe that partly explains why early trailers weighed less than today's. Weight doesn't matter much in your house; could even be an advantage. But in something rolling, not so good. I would guess my 13 is 50 pounds heavier with its OSB floor vs. plywood. And you could subtract another 50-100 pounds if you replaced all the man-made sawdust and glue wood panel products in the cabinetry with plywood. Such substitutions might add $100 - $200 dollars to the cost of your rig depending on how much wood cabinetry you have.

Quality plywood also is more moisture resistant and less prone to rot than OSB. But no wood product will stand continuous moist conditions over months, unless its filled with fungicides, which are chemicals I would want to breath every night. 4000-year-old wood in dry Egyptian tombs is still in good condition. Absence of water is key to longevity. Mold/rot cannot grow without water.
