Didn't some GM execs form a company called Rec-Trans to manufacture those? Seems like I read that once. I enjoy reading about them so wouldn't mind if those with interests in these vehicles just post in the alternate tinkerings area. The alternate tinkering area might be appropriate, as a former Winnebago owner speaking, you are constantly tinkering with a motorhome. I meant that humorously, as I loved mine.
Correcting myself: Googled and found that I my memory was a little off.
