If you get by running two and that is the case while you are running down the road, well then, your bus is sealed up tighter than a jelly jar lid.
Noth'n tighter than that cept (insert ethnic slur here).
Don't complain to me cause it's your unPC mind that just thought that up.
Good for you.
About those windows... Little sun when parked and a cool and quiet feeling while OTR. Just my way and I am cool about it and I mean that pun.
John in the shade
What about a visor? A Visor would offer shade, keep the sun out of the interior a bit more dropping the heat load. If it had some dark windows in it you could still see up at stop lights and low overheads, depending on how far it stuck out. More visor = more wind drag = lower fuel economy.
You see black rock guards on many RV's, in the sun, dark colors transfer a lot of heat into the wall. White or polished metal reflects a lot of heat
Mirror tint on the side glass would also drop the heat load.
Ive never de-skinned an MCI, but on every GM we scrapped, which included a 4104, a 4106, and several transits, and also several AM Generals, I dont recall any insulation around the front of any of those buses. None in the front facing, sides, or upper cap, and none around the stair well.
On this MC5, the underside of the stairwell can easily be seen bare as a newborn babies bottom through the spare wheel well. Bare metal sheet is worse than glass as an insulator.
On several sites I have seen where they removed the front facing skin on an MCI, I do not recall seeing a smidge of insulation. Maybe I missed it?
