I know that ATC and Phoenix have both made flat-bed campers, but to my knowledge, FWC is the only one with a standard model offering. With the flatbed from FWC, there aren't a lot of options, but there are some nice upgrades depending on how you camp. For us, we got the "self contained" option with a toilet inside, mainly for when we're camping at places that aren't remote. My wife also wanted the hot water option, so that was easy. Ceiling fans are also an easy choice for a lot of reasons. The harder to justify are the flush sink/stove and the color options, but we liked those for our use.
