Advice: 2001 Thor Four Winds 31c - Good? Bad?
My wife and I came across a 2001 Thor Four Winds 31c and wondering if there is anything we should be careful of. It's a E450 with a V10. Weren't the early year V10s bad engines? This one has 115K...

Some of the older V10's would spit spark plugs due to poor threads in the head. Maybe have the spark plugs changed as condition of the sale to ensure that you do not have problems. Later versions of this engine had 3 valves per cylinder which gave it more horsepower and also corrected the thread problems in the head. That van will have the 4R100 transmission. If you can find a newer one with the 5R110, you will have less problems. Remember the van chassis may be year older than the assembled RV, so try to get the E450 VIN to see if it is a 2000 (10th digit in the VIN indicates the year).
