I tore out the carpet that was in my '84 13' Scamp
before I replaced the floor. The main carpet was a replacement of the original 80's colors (brown/green/rust), but the original was left in the cabinet under the front bunk. That was kinda of a bugger to get out, but it came out! I also laid down a moisture barrier to separate the new floating flooring from the base.
I ended up using a cheap laminate from Lumber Liquidators which has been standing up pretty well, but I'd really like to put down Allure vinyl strip flooring. Some day.
Attached is a pdf of the measurements I took so I could figure out how much flooring to buy. I came up with a little under 30 sq. ft. Hope this helps.
BTW, where in Minnesota are you? I'm up near Detroit Lakes.
