You don't mention whether you're looking new or 'previously loved'. Right now anything new, in a gas class A, will be on a Ford chassis. Anything built in the last several years will either be the Ford chassis or the Workhorse chassis. Both have their fans. We had an Allegro on a Ford chassis and had no complaints. With the exception of the well documented brake recall issue most Workhorse chassis owners will tell you it is also a fine product. The point I'm slowly working up to is, regardless of make or model, it will be on one of these chassis. What you'll really want to focus on is the floor plan and build quality of the 'house'. Does it work for you, not necessarily what others have or will recommend.
There are a number of bunk models available these days. Any diligent search should leave you with multiple rigs to choose from. As mentioned above, don't hesitate to ask questions. You'll be hard pressed to come up with anything someone hasn't already seen or experienced.
