They are all nice campers but to me the Bigfoot stands out as being a bit different as it is a non-slide camper. That wouldn't work for us as we go off camping to often with uncertain weather and sometimes end up spending significant time in the camper. I've heard nothing but good about the clam shell construction.
As others have noted the tank capacity is lower too. Again, depending on how you use it this may not be a problem and they are not small capacities. I'm assuming it has duel batteries (I couldn't tell from the web site). If it didn't that would be a show stopper for me..
Good luck. It's a nice position to be able to make this choice. I've never heard of an ability to get a replacement cost policy on a camper. I wonder if I could find that around here (and what it would cost)
