I am getting ready to cut holes in ceiling and roof for vents, AC. The question is: Do the wires in the ceiling follow any particular pattern on the MC8? Hate to cut through any wires as im cutting the holes. Do they follow along the structual beams? This would be good because i would not be cutting anywhere there. | ||

If I remember correctly (??) on our MC-6, all the wires in the ceiling were fastened to the structural framimng except for the wires that ran to the speakers. Jack | ||

I removed the interior pannels and added 1in. of foam over the original insulation. I offset all fans and AC cause there is only one main center rib running front to rear and it is necessary to keep it solid, or you need to reinforce the hole you cut. If your 8 had 110V florcesent light in the middle those wires run from the left side top of the window. In the rear above the bathroom there are 1or2 wires going to right rear and down to engine compartment. the wires for exterior lights run above windows on both sides. | ||

Bill, Be sure to use doublers around all the holes and install the doublers before you cut the holes. This helps keep the stressed skin strong and prevents skin warping. | ||

Doublers= a second layer of skin at least about 3" larger than the hole. This is to reinforce the skin where you cut the opening and especiaqlly to prevent the skin from cracking in the corners of the opening. Jack | ||

how about one of those small cutters that they use to cut out holes in drywall or a Dremel tool with that bit? Set bit depth to just go through the ceiling layer and not any deeper. | ||

The dremmel is what i was thinking of using. The 120v wires that ran the florecent lights are now 12v DC to run 12v lights on ceiling. | ||

Jack makes a good point. Also be sure to round the inside of the corners to help stop cracking. | ||

FWIW...PD4106 HEAT BLOWER FIX. The blower for the heat/ac was making a terrible rattle/rumble...thought might be bad bearing in the motor. For clarification, it is located behind a barricade in the tool compartment just aft of drivers front wheel. Took down barricade, cleaned and lubed bearing and shaft...windings looked good...but still made a racket. Removed the divide behind to expose the fan...guess what...old mouse nest..removed the nest, and she quieted right down and ran smoothly. Apparently, weight of the nest was throwing fan out of balance. Just thought I would share in case someone else was experiencing similar noise. | ||

Jim, Had almost the same thing happen to my wife's car, the vibration was fierce. I removed the fan/motor and a dead mouse was inside the fan cage!! End of problem, |
