Very good idea to pass on that one. Something very fishy going on there, you were not getting the whole story. I had a 4100 for 8 years and when I traded it in still looked and ran in prime condition. NO rust anywhere much less rusted out floor. If you find a 4100 I do highly recommend it. Almost 1000 hours and the only thing I had to do was replace the battery after 6 years. And yes, the loader does float.
