What a great find. That looks as good or better than the '65 Safari I found 6 blocks from my house, after searching the country for an ALL ORIGINAL
unit. I am extreamly particular to originality. That's just me.
I urge you to consider NOT
covering the floor with anything permanent, such as 'laminated wood flooring'.
It is so difficult and will soon be near impossible to find an ALL ORIGINAL
I used a triple breathing filter and block sanded (#65 - #220)my original floor tiles, then (using a varnish sponge brush) laid on Future Floor Wax. The tiles came near white after sanding and ended up with a great shine.
Throw rugs will contain most of the camping soil and can shake out, the same if you had a wood floor. Any (real) wood floor can't take wet anyway.
Re-Consider ... ?
Think it through ... Every car or truck I have restored over 20 years always
brought more upon sale because
it was all original. I personally feel that this will be true of vintage coaches in the future when the values skyrocket over the next decade.
Good luck with your new acquisition, it is a beauty.
