    MCI 102-C3 coach to RV - General/Floorplan

    This thread will entail the conversion of an MCI coach bus into an RV. I've had a number of requests asking that I start an online blog of the build, although I do not write nor read blogs. So, here be my Pirate thread. Having been a member of the Pirate community for several years, I know damn well this place tops all others for engineering collaborations and knowledge, as well as the ultimate in criticism where needed.

    Starting from the top - here is what we picked up from an eBay auction. 1990 MCI 102-C3 as retired from a limousine service in Dallas, Texas.

    As you may notice further down in this thread, this is the main topic that relates to us purchasing the bus, tearing it down, and designing the overall floorplan. Everything from the heated floor to the inside of the roof, and everything from the rear wall to the windshield relating to the living quarters will be here. Subtopics are split between Engine Bay, Electrical System, Water System, and Driveline/Suspension.
    Those that followed along with the original thread on Pirate know all too well how a build thread this large can get royally mixed up as parts orders and subjects of the particular time end up completely out of order.

    As it was when we arrived to pick it up. My first lesson in driving a 40-foot vehicle - getting it out of a tight parking spot. Then, exiting the center of Dallas at 5:30pm on a Monday.

    Followed my wife home for all of the drive with the exception of the mountain pass between Walsenburg, CO. and Alamosa, CO. The speedometer isn't OE for MCI, so I couldn't trust it to keep me from getting pulled over.

    Lastly, where it resides now. Registration was a breeze and the lady doing the VIN inspection at the DMV was thoroughly intrigued by the idea of converting one of these metal monsters.

      Current known specs are: 8V92TA Detroit Diesel two-stroke, Allison HT740 four-speed auto, full air ride, and air brakes on all three axles.

      One of the first and foremost big plans are to rip out the OE floor and finalize measurements and plans for a hydronic, radiant heat floor. I'll lay out that idea very soon and all input regarding the design is welcome.

        Nice. Being a 1990 is that electronic controlled DDEC?
        How many gallons of 40w did you go through?
        Fuel mileage?
        I'm curious how much something like that sells for?
        Trailer hitch plans?

          Hydronic radiant heat floor, what are you going to use for the fluid, engine coolant? That with a webasto heater to heat/circulate when the engine is off would be pretty bad ass for a camper heating system.

            Looks like $7000-50,000 from what I found online.

                Got it for $7,500. It is in fact DDEC. I'm not sure yet if it's the I or II version. It smokes a bunch upon cold start, but I'm going to be tracking down the source of the oil next week along with beginning my plans to rid this rig of all the backyard mechanic add-ons that it received. The air box drains have hydraulic lines hooked to them and somebody ran them uphill higher than the supercharger. Haven't really figured accurate mpg just yet since I've only driven it from Dallas to home with an inaccurate speedometer swapped from some other bus.

                For the hydronic floor, the basic idea is steel strap and thick fender washers welded to and sandwiched in between steel sheet. I'm wanting to go with Evan's waterless, but the entire system would need nearly a full drum and that runs around $2,500. Ouch. Peak PG may be better.

                There will be a beefy hitch to tow whatever get-around vehicle we have. A front-mount bike rack, as well. The intercity versions of these has OE bike racks. I may be able to find one cheap through the Denver auctions.

                  Seat removal happened a few days ago. Went crazy fast with my wife and a friend helping. 44 minutes from start to finish, including some pauses for texting a three diaper changes lol. We'll be stripping the covers and cushions off the frames next so the steel can go to the scrap yard and the faux leather used for something else. Overhead parcel racks go next

                    I have thought about something like this but it seems like a bus of that type and size would be limited to paved or very well maintained dirt roads and parking lots with a lot of space. It could be a base camp but not much else. What are your thoughts after driving it?

                      Post the seats and overhead racks on craigslist. Someone may want them, you’ll get more money than scrap, and a lot less work than breaking them all down. If they don’t sell in a couple weeks - then scrap them.

                        I always wondered about clearance on rough roads getting into campsites, too. I'm hoping the full air suspension on this will allow you to raise it when necessary? How loud is that engine? My exposure to 2-stroke Detroits is around old farm equipment that you could hear for 1/2 mile or better. Obviously, on a tour bus, it has to be somewhat controlled.

                        I'm excited to see this happen!

                          This makes me white-knuckle it in my Focus. Can't imagine how that was in the bus.

                            That looks like an amazing amount of machine for 7k, I hope it doesn't 1000 dollar you to death, I am guessing everything on that is expensive to deal with.

                            Were those seats held in place by L track/airline track fittings?

                              This is my experience from the outside of an MCI 2 stroke bus! I followed one onto a highway once and it definitely drowned out the straightpiped Dmax I was in, along with the radio. They must have some serious noise abatement between the engine and passenger compartment.

                              Either way this is a pretty awesome build, looking forward to what you come up with. I kicked around something similar but decided against it, as many of the campgrounds I go to wouldnt fit such a beast.
