If I had bought this on my 16th birthday I don't think the fiberglass cap would pay for itself by fuel savings in my lifetime. I just wondered if there some other benefit that I was unaware of, besides good looks.
Columbus is manufactured by Palomino, which is now a Forest River Div. DW & I have followed them for about 2 years. They seem to have a good track record & offer very nice features standard (such as convection/microwave, etc) at a good price point.
