There was an ACE with a similar bike garage back around 2012 ~ 2014 if I recall correctly, but after that they moved the generator to very rear corner and ruined the pass-though for taller bikes, and especially for tandems.
Damon had a few large motorhomes with nice-size bike garage but most don’t have a flat floor which would make loading tandems or taller bikes more difficult.
One exception was the Avanti 3106 which has a great garage pictured below. They seem to have made the effort to drop the rear frame extension to provide a taller Euro-style garage compartment with a flat floor. Like the larger Serrano, these Avanti were also front engine diesels which were very loud. For us these motorhomes at just over 30 feet were a bit too large.
