Dragon Quest Five and Six help

Dragon Quest 5 Problem:
-My wagon seems to have disappeared. I’ve gotten along without it, but now Bianca has joined my group as I’m getting the water ring, and I can’t use her since she is with my wagon. I tried using return a lot, and walking to different towns but I can’t seem to get it back. I’m sure that I will have to start over, but it is my last hope that maybe someone knows how to get it back.

You didn’t use any cheats or hacks did you? If you did and dont have a save state predating the cheats, then I suggest starting over since you are not too far into the game yet.
