I purchased my first FWC back in 1983, a new Grandby. After over twenty years of use I can say they build a great camper. It is simple, rugged, minimalist and as the name suggests, a four wheel drive back roads type of camper. I recently purchased a new FWC Hawk and after two years of back country use I can say the new ones are even better, with more amenities.....but as I said leaning more the minimalistic side of things.
This probably isn't the best place for reviews of back country campers. I would suggest, in addition to Expo,
http://www.wanderthewest.com/forum/forum/17-truck-campers/As far as a comparison to the Phoenix campers, I looked closely at all the major players at the show here in Denver before my purchase. Honestly, the fit and finish on the Phoenix was a non starter for me.
As a side note, the reputation and resale value, I think, is unparalleled in the market.....
In any case I sold my over 20 year old FWC for more than I paid for it in less than two hours on CL.
My new one:
2012 Chevy 2500HD LTZ CCSB 4x4 gas
2012 Four Wheel Camper Hawk
2008 Harley Street Glide
