Way back when, took my 2005 to Doubletree for factory work and was told the Cruiser plant just north of I-90 and west of the n/s road was owned by Dave Faught. A lot of this goes back to the old Sunnybrook name/plant as the origin of Doubletree, if I recall correctly. Unsure of how the change took place, but I have always thought that Faught left SB to start Doubletree, leaving Elvie Fry to run SB. SB later went out of business and even later, the name was bought by Winnebago.
SBs, in their time, were noted to be better-quality units--I owned 2 of the SB TTs --and I bought my '05 Suites based on the knowledge that the owner came from that company.
Doubletree later was sued/told to 'cease and desist' using the name by the Doubletree hotel chain, and thus DRV name came about.
Porkchop can probably correct some of the above if I have mis-stated anything.
Whatever, Thor ultimately owns all of it....Heartland/DRV/Cruiser
