A very good question ... and you know I can't remember if that was discussed in this thread about flooring change over.
Well I thought I had a link ,, but can't find it
Please do a forum search for the thread " Hardwood Everywhere"
If I find the link soon I'll post it .
Found it and back in time to add it here.
If you do use the search , you'll find every post here in the forums about wood floors in motor homes.
