If you are going to make a really cheap top, I guess it might be an advantage to give it a name that implies it comes from a country where everything is precision crafted and really expensive.
"Swiss" is an Indiana company and they've been in business for about 40 years. Their business is local/regional.
Like utility trailers, camper tops have two tiers. There are national brands with big advertising and distribution expenses, and there are local and regional manufacturers that have a small number of local dealers or sell direct. The local guys have lower expenses, can sell at local prices.
Ask your Swiss dealer to give a reference from a local buyer, if you are concerned about quality. It is not a national brand
