Hmmm. Before I bought my 2000 Sunnybrook in 1999, I joined the RV Consumers Group to get their info. The Sunnybrook was the ONLY trailer that was rated for "seasonal" use. There were a very few brands, Teton Homes, etc, that were rated for "full time". All the others, including Excel, were rated only for "vacation" or "weekend" use. Have the ratings changed that much in the last few years? I don't know anything about Excel but the Sunnybrooks I have seen (including mine) are first rate.
