    Any one know if a newer 63in unibilt ultra sleeper from a 389/388 will fit on a 379(63 inch ultra unibilt sleeper)? I know electrical and hoses is different but are the mounts the same on the front and back.? It's just cheaper to just switch out sleepers than repair old 2002 sleeper.

    I think the front upper sleeper to cab mount is slightly higher on the newer models. It probably wouldn't be that hard to make a bracket to connect the two. Just have to find one and do some measuring.
