As some have mentioned, the RTT is a great option, but when the weather sets in, it's sucks bigtime. Putting away a wet tent, while it's raining or snowing is a pain. Climbing to the truck roof to do it is seriously frustrating. Doing it with your wife is total hell... Other than that it's great. Having a big awning with walls made it a more usable setup but also meant more crap to put away wet.
Since we got our camper, we've enjoyed a small piece of heaven for the following reasons: it takes less than 10 seconds to set up. We're comfortable and securefrom the elements. While the cooling fan and heater unit are a matter of comfort, they are also a matter of sustainability to remain out longer. Staying cold/wet or overheated is risking a premature ending to your adventure. Our setup is created with a mobile kitchen concept. Nothing built into the camper. Portable faucet, sink and stove. Everything is used outside until the weather rolls in, then can be used inside where the cabinets and furniture are designed to easily use the same kitchen gear. Easy, reliable, wife loves it.
To address your question, we decided against the FWC not because of quality (there are obviously many happy customers), but because of design preferences. The design of the overhang, the entry door, the bed, the cabinets, the vertical roof, aluminum frame and thin walls and lack of storage all effected our choice. We paid too much for our choice of camper because the currency exchange rate was pretty bad at the time of purchase, but at current rates, our camper could be had for about the same or less than a FWC.
