It is now a proven fact that my Smart Wheel Cruise Control does not like heat. For the fourth consecutive time that I have driven through Dateland on I8 with the outside temp at 115 the cruise has quit. It's quite disturbing when it happens because as it shuts off it's like your out of gas. Gets your attention fast. Everything else works fine and the Cruise returns when it cools down.
You might say stop driving in those conditions at that location. I say that I am on my way to my mother-in -laws and my BH would object vociferously.

A more drastic suggestion to resolve the mother-in-law situation would probably create more problems than it solves, so for now I'd say:
Live w/the cruise problem, and save your own life.

Here's another thought- if yours is like mine, its mounted on the metal firewall bulkhead, and the bulkhead has a noise attenuating blanket glued on the forward (gen set) side that is black & no doubt highly susceptible to accumulating heat. Try insulating the forward side of the bulkhead where the CC/SmartWheel box is. If that doesn't work, unship the box & insulate between the box & wall when re-attaching. You could use foam packing sheet for the insulation. Gotta be only a few degrees causing this, and small insulation shim should fix it.
If that doesn't work, and you are still non-plused, PM me for the afore-mentioned alternative solution methodology.

EM & Chris - That is sort of what I was going to say. THe SW control box is behind the PS side panel under the dashboard, panel is held on with a couple of screws. The box (cannot remember if mine is mounted or just laying in there) is in/on that side of the coach under dash area. Like Mike said, remvoe the box carefully, put some insulation behind the place where is resides and then screw it back up. That should solve the problem, or you can figure out a place to remount if, or secure it off the firewall.
NOTE: Near where that box is located is a HIGH-AMP RED wire, with at least 50 AMPs of DC current coming through it. Turn off all the power to the coach as a safety caution before poking around in there, you don't want to get shocked by that DC, it could stop your heart.

Probably the best insulation for its size is Dynamat, used to insulate sound and heat for electronics and sound applications. You can find it in 12" squares with a self-adhesive backing at stereo shops. Several folks on this forum have also used it to control heat from the engine into the bedroom and to insulate the plenum in the heating system. It isn't very thick, but works amazingly. Tis pricey per square foot, but you need less than one piece.
