But before you do that (or call Gear Vendors), hook up a vacuum gauge and drive around a while to see how it responds to your driving habits. An example, if your driving at 60 and 3000rpms, and you're pulling 15"hg, and then you're driving at 65 and 3200rpms and pulling 17"hg, you are actually MORE efficient at 65 than 60. If the opposite were the case, then you are more efficient at 60mph... Get what I mean? Eric Correct me if I'm wrong but how could you get higher manifold pressure if the only factor that changes is increasing throttle position to increase the RPMs? Wouldn't the increased throttle position lower the manifold pressure? My understanding is that throttle position on a non-computerized, carbureted vehicle determines manifold pressure. I don't think I have ever seen pressure increases while throttle positions increases unless other factors are involved, like gear changes, or in the instance of newer vehicles timing changes due to computer control, etc. This is just my understanding and would be very interested in the correct information!Re: How many of us are there?

Fleetwood has to give it an identity and uses a numbering system all their own, hence the G07 number. Just a small clarification of the info. The C designation is for a GVW >10,000 lbs, not just 10,001 lbs. I believe most in this rating had a GVW rating of 10,500 lbs with a 3,800 lb front axle rating and a 7,200 lb rear axle rating.Re: How many of us are there?

They're mainly steel framing with a few wood sub-frame members and then rigid fiberglass sides. Mine has 5 fiberglass panels: top, rear, both sides, and one that continues the sides around the cab.Re: How many of us are there?

I can't find an idiot light for it anywhere, but upon close inspection I could make out a 'full' line just above the oval slot at the tip of the dipstick where the sensor is located. Mine also leaks if I park driver's side low. Hope this helps, dave My '78 also has the diptstick with a sensor. I have included info from the Dodge service manual about the system (see below). The light is normally located just below the radio in the center of the dash. On mine there is a very dark red plastic strip that has room for several indicator lights. Only one is the warning light and it is difficult to see in daylight. Excerpt from service manual: "Transmission Warning Light A transmission warning light is located on the instrument panel to alert the driver that the transmission requires servicing. The light indicates the fluid level is low. Warning Light Operation Turn the key to the start position. The warning light should come on while cranking the engine and should go out when the key is released to the run position. If the light does not come on while cranking or failes to go out with the key in the run position, the warning system should be checked."Re: How many of us are there? Owners of Dodge based RV's?

Does anyone know what the torque specs are for the drums and the lug nuts. I can't find anything on them. Thank in advance for any info....Jerry CB300 & MB300 with 1/2"-20TPI and 13/16" hex nuts: 85 to 125 Ft-Lbs. CB300, MB300, & MB400 with 5/8"-18TPI studs and 1-1/8" hex nuts: 300 to 350 Ft-Lbs.

I've got a 81 Establishment 26' that has a 78 Dodge M-400 (iirc) chassis with a 440 and only 24,000 miles! .... Budd From the profile picture is looks pretty nice. I even like the computer dam!!! Is that a bunk bed model? Also, just a small comment on your description, I believe it should be the MB400 and not the M-400. I think the M-400 was for the Class A chassis. Also, are you sure that it is a 1981 model? The picture you have on your profile page is of a 1977 or earlier Dodge chassis. In 1978 Dodge changed the sheet metal and front grille on their vans to a wider look. If the coach is a 1981 then the mfg apparently had a few older Dodges laying around!!!Re: How many of us are there?

An F40 is the next model up which equates to an MB400. The F30 is the chassis used for the MB300.Re: How many of us are there? Owners of Dodge based RV's?

Owners of Dodge based RV's? MasterBoondocker wrote: Oh-Tay !! ..... HOW well do those baga "live" ? ....... and do they always have separate ports to fill each bag ? ... The air bags are great. If I don't fill them up then the MH sways back and forth and leans in the corners. Putting in about 70psi increases ride height a little, elimates the swaying, and decreases the leaning when cornering. Makes a big difference. Too much pressure though and the ride suffers! :) The factory installed them so each bag is filled independently from air valves (tire valves) mounted on the lip of the wheel well. This is so the air doesn't bleed from one bag to the other during cornering and making things worse. An air compressor can be installed that will allow the bags to be filled automatically and controlled from the dash. These are the original bags which were installed new in 1978 so they seem to good longevity.Re: How many of us are there? Owners of Dodge based RV's? MasterBoondocker wrote: RHRV ...I would double-check that valve .... LOTS of people have tried to use air-shocks. NOT the plan here - in RV-Land ! Thanks for the concern MB but that's not the issue here. Robinhood installed Firestones's air bag system on the rear suspension as standard equipment. Same air bag system being used on many of the newer Class A coaches. The Air bags are in addition to the standard hydraulic shocks. This same air bag system is available from RV suppiers for most, if not all the motorhomes out there.
