Been a while, but I am back trying to figure out the last two things on my RV.
First up, I figured out that I was a bit off base. This 1980 Winnebago Minnie Winnie is truly an odd duck. It is not the CB300 chassis I originally thought, this tiny 20 footer is on an MB400 chassis. It is also not a small block, the little thing is powered by a 1978 440-1. Truly a rig built from leftover parts hanging around.
Anyway, I pulled it out of storage to begin prepping for Sturgis next month. I found my dash panel lights were no longer working. I rotated the knob back and forth, and the knob feels right and activates the interior light at the right spot, but nothing from the dash. Is there a common failure point I need to look at? I'm hoping rodents didn't munch on the wiring.
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?
Anyway, since I started here, I have made a custom rear bumper with class 3 hitch, beefed up the extensions, wired in a brake controller, added LED lights all around, to include 4" round stop/tail/turn LEDs with integral white LED reverse in the centers, put in LED headlights (HD Daymaker style, only rectangular), added a dorm fridge, fixed the furnace, replaced the water heater, added a rooftop A/C, installed satellite radio and a CB with WX, changed to modern wheels off a late 80's ram D350 with 215/85R16 tires, built mirror arm extensions to get the mirrors outside the body and actually see down the sides and see the trailer... and finally, I bought the fabric this week to begin reupholstering the entire interior, since the original fabric is falling apart.
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.
