Outdoors RV, based on construction, there is a major difference, watch their video.
As far as dealing, you'll need to consider a road trip, best to get to Pendleton, OR after having a phone conversation with Thompson RV. Make it a vacation. On your Black Rock, also look at the Timber Ridge 23DBS, (exact same body as the Black Rock 23BKS). FWIW, Thompson orders every Timber Ridge with the X4 offroad pack and mountain storage system. Great folks, and lots of long distance buyers.
Crist RV in Mesa, has a new 2016 Creek Side 23DBS, again identical body. ORV re-aligned models for 2017, and the Creekside 23DBS became Timber Ridge 23DBS. Findlay in Las Vegas, probably could order whatever you wanted. ORV's are built by model runs, only certain times of the year.
Tundra, great truck, but read this funny (but serious and factual) post. Note it is in the Outdoors RV owners sub-forum, great resource, yes on that "other" rv site.
ORV cost me $ 53K!
