A122 Subfloor


I will be picking up my new Rockwood A122 on Friday. I am really looking forward to getting back into camping and the A frame looks like it is going to be a blast. One question I have (of many) deals with the subfloor. I noticed while Inspecting the underside of the A122, that the bottom side of the subfloor is exposed to the elements. On my old travel trailer, the bottom of the trailer was covered by a moisture barrier, protecting the subfloor from splashes and road debris. I am wondering if it would be advantages to spray it with undercoating, or if is left this way for a reason. Any ideas are appreciated.

Welcome and congrats getting a cool rig!

If you put any coating there, you'll void the warranty. I believe that part has a 25 year warranty. Don't forget to get the FR lifetime warranty for only $100.

Enjoy your new TT!

As ko777 said, the subfloor must be left uncoated so it can breathe. Among your materials on Friday should be info about the floor including the part about its warranty. We all had the same worry initially too, so you're right on target with the rest of us. After 3 years, I no longer worry about it.
Be sure to come back often and ask whatever's on your mind or just shoot the breeze. This is a friendly bunch. Welcome!

Congrats on your new camper. I just bought an A122S. I have been out three nights now. I'd probably sleep in it while at home except my DW is already questioning whether I love the camper more than her. I do reserve the right to use it for napping without questioning.

Dave, congrats on your new trailer! Be sure to read your manual and send in any warranty paperwork on the individual appliances...The fridge, fan, furnace had seperate warranties to be sent to the company that made them. Dont apply any undercoat to the floor-not if you want it covered under warranty.

LOL Tom! My DH often finds me in his shop, sitting inside El Beso! Conversation goes something like this: "Whatcha doin, just sitting?" And I say "Yep" (he knows I am daydreaming and planning her next personalized change....I think not much will surprise him since applying those swinging monkeys on her side for me...haha

Thanks for all the advise. I will be sure to send in all my warranties. Although, I'm still leery about the exposed compressed board on her undersides. I'll leave it alone. I had a 17 foot Layton a few years ago. It had a roof leak in one of the seams that I did not catch one winter. When we took her out in the spring, the whole front halve of the floor was rotted. Come to think of it, the moisture barrier trapped the water and probably accelerated the rot. 😟 So, maybe it is a good thing that there is no moisture barrier. 😊 At any rate, I am looking forward to getting back into the camping saddle again. Thanks again for the replies.

This comes up from time to time. An old post here about it.
in the woods!!

OSB does not delaminate like plywood might because it is not a laminated product. It is also not particleboard although it can often be confused with it. Weyerhaeuser Structurewood for flooring is a one-piece RV flooring wood, i think it comes in up to 45 foot sheets. It has extra resin and wax to resist normal weather conditions. I have not seen anything about this product specifically recommending or condoning additional sealing. I don't have the flooring warranty handy, but I'm sure if you called forest river inc they could provide the details you need.

rawlus, this is really good information. I was wondering if the subfloor was made of specially treated material. Thanks, it makes me more confident that this is an excellent product.

Similar to the decking I used in my home, lumber yard had a piece sitting in water to demonstrate durability. Unlike normal OSB product or typical grade CDX or plywood this specialty product resists water even when a butt end is exposed. Do not treat it!
