The statement that says "road tested heard noise from converter" is a little bottersome. Most motorhomes may have 2 converters. One might be the torque converter in the front of the transmission. The other might be the electrical device that converts 120 Volt to 12 volt.
I believe this was fixed too since it was 13K miles ago. We didn't hear anything test driving it, it was pretty quiet. We are going to see if we can get the previous owners information off some of the bills to call them.
I was wondering what a long block was. Thanks for all the replies so far.
