I don't have any idea where you are located.
Steves RV in Lacombe La (40 miles north of New Orleans) routinely orders them, and usually has campers with them in stock.
He also has very good prices (close to the internet wholesalers, but not quite as he also offers service). I've bought 2 campers there and have been very impressed with the quality of their dealership as well as the price/service balance.
You can check his inventory here: http://www.stevesrv.com/inventory.ph...&submit=Search
He is showing the camper you are looking for in the Super Lite with a Cequent Pin box, and it is listed as "short bed truck". Not familiar with Cequent but it may work like the Reese.
One other thing to consider - I have only noticed this setup on the "Super Lite" models, and the Mor Ryde on the non "Lite" models. Don't know if it's only available this way, or just a coincidence.
Find a dealer that has a good reputation who is close enough to use regularly & talk to them about it. They will know.
