Four Winds made very nice RV's independantly for many years and the Ford E350 is a time tested cab chassis. The 460 is a massive power plant, but not known for super good MPG. In Ford Trucks, owners have said for years about the 460, "so much power, you can pass most anything...except a gas station."
Four Winds was acquired by Thor industries many years ago, and you can see many Four Winds models under the new Thor Motor Coach (TMC) brand. This is important, because the company was bought and continued vs. Being another RV company that ceased to exist.
Like any used RV, you want to have it checked by someone that knows RV systems. If it is all new to you, then it is smart to pay the $100-$300 for a full check.
These tough little RV's can go many places big Class A's cannot. If the engine and trans are healthy, I would have no problem with a trip across the US.
