Bill, Sounds like you're doing your homework. I can give you a few tips that worked for me.
1. Spend time on ebay, craigslist, ForSale ads on this site and http://www.fiberglass-rv-4sale.com
so you can 'tour' the trailers using their photos. It will give you a good feeling for the trailers, the finishes and the little cosmetic 'oddities' that make each brand unique.
2. Explore around the photos and posts on this website, of all the refurbs that have been done by members of this group.
3. See if you can find an egg gathering and stop on in. Most FG'ers are more than happy to show off their 'eggs'. (There are ralley locations listed on this site). It may mean that you invest in some gas, and a hotel room for the weekend.
4. Go to the website links for the trailer models that are listed on this forum, and take note of dimensions and sizes. Then use those measurments to 'lay out' the trailer on your living room floor to get an idea as to how big/small it actually is.
5. Hopefully this will help you be more comfortable making a decision on a purchase, whether or not you actually physically visit it before you buy. (I bought mine off Ebay)
Good luck, your trailer is out there!
