Welcome to the forum and irv2.
The
ALLSTAR coach maybe up your line has large bed for adults twin beds above deck and coach up front, plus we had kids in sleeping bags on floor space available.
We traveled across Canada and U.S.A. pulling a sleeper popup that would sleep five of our foster children also.
We would rent vans when ever we needed one or used MH for commute to destination.
You can find Allstar DP's in Brochures 2007 to 2010 time period
in this link for pass Newmar MH's.
The popup we had was a Dutchman made in 2000 and checked it yesterday and still in good shape for a load to a family in need from LA.
Most MH may have a convertible dinette,main bed and coach. tough for big family
Good luck in your hunt.
