Re: Journey Begins - 1988 Crown Conversion

I got pulled over by a CHP DOT cop because the bus was yellow.

Re: Journey Begins - 1988 Crown Conversion

See, it is just not worth the hassle and expense if you do a yellow paint job and some guy with a badge pulls you over because the yellow is toooooo close to school bus yellow.

HEATER CORE FINALLY REPLACED

Progress can seem very slow at times with conversions. We found a new heater core for the Crown and replaced it. Black and new. The old one had clearly seen better days and was dirty, old and streaked with gunk.

SANDING IN THE FRONT AND SIDE PANELS

Attached are picture of the sanding job in the front. In addition, the interiors of the side panels are also getting sanded. I know most people will never see the inside, but we will. So, we want the interiors of the panels to be as nice as the exterior.

HOLES FOR AIR CONDITIONING - OH GOD!!!

Scary, scary, scary. Oooooooooooopppppppppps is not allowed. We debated a great deal about where to put the air conditioners. We bought two 15,000 btu low profile units from Dometic. We read a great deal from various sources about where to put the units. We decided to put one near the front, in the front 25% of the bus length. We placed another about 1/3rd of the way from the very back of the bus. This should create good air flow throughout the bus in hot weather.

Of course, Crowns did not come equipped with dash air conditioning. We looked at putting in some aftermarket units, but decided it was just too much hassle and experimentation. That is why we placed the front air conditioning unit a little closer to the front than we originally planned (the front 1/3rd of the bus length). Plus, we have been doing some research and 3M has a great clear tinting film for front windshields that cuts UV rays by 99.7% and heat transfer by 60%. With this clear coating on the giant front windshield, we should not get the heat problems usually associated with busses.

The units we purchased include heating elements for those chilly nights. The difference in having this option or not was minimal, so we figured why not go for it, even if we will not use the heating portion very much. We are planning a built in electric fire place/heater unit in the same cabinet that will house the pop up flat screen TV monitor. That will usually provide all the heat we might need. We are not planning to visit the Alaskan wilderness or other bitterly cold places during the Winter.

Re: Journey Begins - 1988 Crown Conversion

If your heading to Alaska, I would be dropping that ceiling, and spray foaming your interior. Without a good thermal break, the radiant cold takes its toll on every muscle in your body. I'm living in a uninsulated bedroom right now. Enduring this every night makes me want to get my bus done sooner.

Re: Journey Begins - 1988 Crown Conversion

Crowns are not built like other busses. Putting additional insulation in the ceiling requires removing thousands of screws and rivits to remove the headliner. The roof structure has more than just ribbing. It is more akin to a honeycomb of structural support. So, to properly insulate every cell and void you have to remove the headliner. My bus has about two inches of insulation already in the roof. Another Crown conversion on this site had none. So, it must have been an option from the factory.

We intend to place some addition insulation on the headliner before covering it with flexible paneling that will be covered with padded faux leather. That is the current idea for the ceiling.

The boot or rear compartment is also going to get insulated to keep the cold and heat from getting into the interior. The sides are also going to get insulated before getting covered. Finally, we intend to spray foam insulate under the bus. We are told that there are products for that. We want to make sure that the frame is not covered so it can periodically be inspected for cracks. The bus is 25 years old and we are realists.

We recognize that even with all this effort some environments will still not be suitable for our conversion. So we do not intend to visit Death Valley in August or Alaska in January. It is really about how much you want to spend. I am sure that with enough money and effort our Crown could be insulated against the most extremes of weather. Since my bucket list does not include experiencing 130 in Summer or -50 in Winter (I am a Northern California wimp) I think we will be fine.

Re: Journey Begins - 1988 Crown Conversion

How are you going to run your wiring for the ac units? if your not pulling your roof panels off is it going to be exposed or are you planning on covering it with you leather padding?

Re: Journey Begins - 1988 Crown Conversion

That is a good question. Frankly, I was going to call Brown Crown for advice. He converted a Crown and he had an air conditioning unit on top. I think it would be a bear to thread the wires between the headliner and the roof down to the side chase area (that is where the dome lights are that run down the sides inside the bus. When you cut the holes you can see the gap between the headliner and roof. However, I am concerned about hitting metal ribs and roof bracing. Running the wiring down the headliner and then covering with the insulation and the padded paneling should work. But, again, Brown Crown is my guide on this.
