Welcome to our forum.
Have you not checked with your local marquis dealer? or called Marquis Corporation???
I am in need of a replacement cover for my 2001 Marquis Spirit Spa. I have narrowed down my choices to RHTubs and The Cover guy in Canada. Both seem to have some very good products.
Both products seem to be similar in construction, features, and price.
The Cover guy seems to have a few of the features that the RHtub site has as options, such as a reflective heat lining and 2 lb foam density.
It is very difficult to find accurate information sometimes. This is one of the reasons why I like this and other forums I visit. You get real people with real opinions. Not just a bunch of marketing material.MB
