I have a 2018 Tiffin 32 SA on a Ford chassis. I parked it to flush tanks out and when I got back in it to move it the transmission lever on the steering column was locked up - the only way to put it in gear is to crawl under the coach and shift the transmission by hand with the wife holding brake down with the emergency brake also set . I would appreciate any insight as to problem and your opinion as if it’s safe to drive to get it worked on after getting it in gear Thanks Eng82
