After further thought ! I do Have a 55 model wagon, the dogs love Her. They (the dogs) pile up on her and when she comes out of storage (the couch) they are ready to go ! Her motor is pretty solid, it's her transmission that is hard to get in gear, I've tried prodding but she won't budge from the (couch & tv). I'm still hopefully that I can wrench her back in shape and out of the Wagon Train and Gunsmoke funk she is in.
