Advice: 2001 Thor Four Winds 31c - Good? Bad?

Thanks for the info.

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).

While this is a toy hauler it's also a Class C so many of the posts can be found in that sub-forum. I'm not finding anything over the past year, but I ran a search from the archives, you can find those posts and probably some off topic items, *here*

Check out this thread, *Here*

Not sure about them being bad, but the V-10s after 2003 were suppose to have some changes that made them better, more power for one. Not sure that I would purchase one with those kind of miles on it.
