28-30 diesel pusher

i have a 1992 Xplorer 26' class A cummins pusher, and i have a friend who is looking for a 28-30' class A diesel pusher. i have been trying to find out the names and models of any short 28-30' diesel pushers, i know Xplorer also made a 28' but i haven't been able to find one, same with Barth, they made a 28-30' cummins diesel pusher, are there any other makes? thanks for your help Gerry
