Finally, has anyone figured out how to diagnose and repair the cruise control on these? Mine has never worked since I owned it. The little vacuum diaphragm seems to hold vacuum and the supply is there. Nothing happens when I activate the cruise... no clicks, ticks, hums, or anything else mechanical, and the speed obviously falls to idle when activated going down the road. -or- would I be better off trying to retrofit aftermarket cruise control?

In the next year, I hope to source a built 47RH transmission with adjustable pressure and vacuum switches to automatically control OD and TCC Lock. Hopefully this will bring me up from the dismal 5.5 mpg I get towing the pictured trailer with one Harley inside at 60 and allow me to cruise at 65-70 without the engine screaming for mercy at those RPMs.
I doubt you want an OD unit on one of these RVs, especially towing the trailer. The old mantra - tow in drive, keep your trans alive - is still true today. We had a 47RH in our '90 Dodge B250 with a 360, and the OD unit was a common failure point. And the failure on ours, too - my husband forgot the mantra and used the OD while towing our raceboat (open) trailer, which weighs a lot less than your enclosed trailer. If you could find a Gear Vendor overdrive unit, which bolts onto the 727, you'd be better off. They're built for heavy-duty use.
