Ditch the Groucho, Get the Coucho...
We have a similar 1994 30' Excella, and the previous owner discarded the "groucho" (because it was uncomfortable and made people grouchy when they slept on it) with a double recliner.
Here's a tip: Remove the bottom part of the gaucho but save the top to cover the battery boxes. It's a small, but useful advantage--it'll give you an extra three inches.
As for the resale deal: We paid twice what the NADA said for our unit. (notice that "NADA" is the word for "nothing" in Spanish, which is a clue to its relevance). Our Excella did not have the gaucho, but was in very good overall shape, and we didn't blink an eye at the difference. These rigs are not like classic cars, in my humble opinion. People buy them for their utility and quality. The dual recliners are very comfortable, and by moving the table from curb side to street side, we can use it now too.
Good luck! Suggest worrying more about how you'll enjoy your unit and not about resale. I think your '94 will hold its value and then some over the years!
