Builder board??

[Les Audouins]

Hello! I have a 98 Eagle 12 SO that I just got and renovating. Does anyone know what the thick cardboard like material is that lines the front and back aluminum? The sides seem to be lined using luan boards. My best guess is heavy duty builder’s board?!

Honestly, don’t think it matters, I would find something that works and use it. Plenty of more modern materials that are lighter and stronger that can be used.

Yeah but I can’t figure out what to replace it with since I don’t know what purpose it served. I think it was to strengthen resistance and reduce the possibility of dents. Let me know if you have a theory! Thanks for your reply.

Perhaps a thin Masonite material would bend enough, to form the curve without breaking.

When I re-built the rear end of my 89 Jayco 1006, I used 1/2" plywood in the large flat area of the tail lights (mainly to have something to screw the lights to) and in the bottom beveled area but I simply removed all the fiberboard and did not replace it. The corrugated metal is pretty stiff and the plywood backs it up.

Thanks for the photo. If it worked for you I think I’ll do the same. Remove the fiberboard and reinforce the areas where inlets, tail lights and the spare tire go with 1/2” plywood. Onwards!

Holee crap. Interesting I’m asking similar questions in another thread. Can’t imagine the time it would take to accomplish this.

It's really not that bad. Just remove the corner trim and pull all the staples holding the skins and they come right off. I had to rebuild the rotted right rear corner on mine which also involved several of the cross members but it was not that hard.

We're just removing from a 2020 all the aluminum siding due hail damage (none Jayco), then you know for sure how poor the low end is build (25K). Start renovating the moment you buy. Studs and crossmembers bowed so bad we will replace. Time this industry smartens up and give customers their monies worth.

It’s not that bad. The framing can go quickly and it’s rewarding when you know it’s done much better than the original which just used a gazillion staples everywhere to hold it together. So far the most time consuming and boring task has been scraping off that darn fiberboard from the aluminum!
