I'd like to share what I know about Filon.
It is made up of very thin sheets of Luan wood (like that used for the very light weight closet doors in some houses)
Saying that the Luon is 3/16" thick is being generous.
Some of the sheets were 20' x 8' or 10'
There is a"flash coat" of fiberglas resin on one side... now Filon.
This leaves a very thin wood surface facing the wood frame on the inside of the the camper.... it made it easy to glue the Filon to the frame.
In a perfect world this works great.
Of course...we don't live in a perfect world... humidity and water leaks are absorbed into the luon... allowing it to swell and seperate at the glue joints.
Where does the humidity come from?
Breathing, cooking, burning propane in the stove, showers, and natures humidity.
And of course water leaks from joints that need recaulked... fresh water or waste water leaks are more obvious. And owner caused damage.
Over time the filon wood backing shreads... leaving a very thin flash coat of fibreglas resin that is no long totally glued to the frame.
Add in road vibrations, pot holes, hurricane force winds when we have a combined forward speed and head winds of 76 mph or more.
When we had aluminum skins we had screws holdin the skin on... putting a screw in the Filon would hasten the failure of the Filon.
It appears to me that any 10 yeaar old camper with a filon skin is at risk of failing. I'm sure that was part of the rational to go to a metal frame and Adzel skin.
No one wants to hear this... it affects the resale value of the camper and long range durability.
I have observed this first hand on many campers.
I have had many people contact me over the years about purchasing TC's, particularly the Lance 1161/1191 series
I have always tried to get them to avoid the models before 2005This will never affect my 1161's resale... we will eventually give it away... we never sell cars and trucks... we give them away.
I contacted Lance Customer Service Center in Feruary of this year to inqire about having our 2003 Lance 1161 reskined...
... we mutually agreed that it would cost $15,000... and they (Lance) couldn't do it with Adzel
It is not our faliure... it's the Filon and time.Sorry to admit this in the open forum..
.... but it bothers me to see Capt PJ (pjay) get blamed for something out of his control... he has taken very good care of his camper. Janet and I have roamed the mountains with him and his wife... I have pictures of me on the roof of his 1161... washing and inspecting it. It was in good shape.
