How many of us are there? Owners of Dodge based RV's?

You guys are making good progress. My repair manual came the other day, so I can start planning what I need/want to do with the engine. I decided to plug in the electrical and try running the AC to dry out the inside of the coach (and not fall over from heatstroke) and I discovered something odd. The end of cord for the electrical service has been replaced (not very well), not only that but its been swapped to your typical 120V Three prong plug like you use in the house/can be plugged into an extension cord. Am I correct in assuming that this is NOT normal for an RV? I was under the assumption they used some weird plug. Also not sure if it is 30A or 50A. I am operating the assumption for right now that it is 30, but I will have to be sure before I do anything.

So I guess I need to replace the cord (or at very least the end) before I can safely take advantage of "shore power" (I dunno what the RV equivalent is). I talked to the buddy who is storing it for me. His electrical panel is very close to where the RV is parked, so I am looking into having a hookup installed on that corner of the house.

Couldn't resist the likeness to The Acme Bomb. There's actually an artist's rendition of that Bomb in the art museum at Governor's Palace in Santa Fe NM. A 3D model, not just a painting.

Saw a rather tame Roadrunner in Blue Diamond NM looking for a marker for the El Camino Real (The Royal Road) trail. Mentioned the bird to a local lady. She said "Oh that's a begging roadrunner. Surprised he's not at my back door seeing what he can get from my husband.

You should get Road Runner horns!

So your rig is the Road Runner then? :D

Out with the old & in with the new fuel filler housing



Something's wrong here. A re-wiring was in order. The 110v receptacle on the panel was melted too. It's getting replaced with a new Leviton receptacle.



It was a lot of work, but Dana 70's sure do look pretty, when they're cleaned & painted!

Extra Credit Question: Why is Reservoir labeled ACME?

Okay, that makes sense, the check valve is tee’d.

No idea on Acme, other than they’ve been in the A/C business for years.

Dorman Reservoir, where that black hose runs from the Check Valve, which is also a Tee, parallel to the bottom of the picture, behind Oil Filler, Wiring Harness and Transmission Dipstick, to the single connector on the lower left corner of the pictured Dorman reserve tank. Here's the Dorman 47150 Check Valve and the Dorman 47077 Vacuum Canister

Circuit is Source (engine intake manifold) to Check Valve. Then Check Valve to Tee. Tee Branches to Vehicle system (HVAC, Cruise) and to Reservoir. Vacuum in this little system rises to adequate on Cruising and maximum on Deceleration. Would do this without Check Valve and Reservoir in those two states, but would fall to Unacceptable on Acceleration and Climbing. Reservoir and Check Valve store vacuum up till vehicle gets back to Cruising or Deceleration.

You can use Dorman 47076 . Same Circuit except 47076 replaces Check Valve and Tee.

"HELP" line products from Dorman has two of those spherical vacuum reservoirs. One has its own built in check valve and has two hose connections. The other works with an external check valve and only one connection. With a little rearranging, you can use either. I like to use the one-connection one with a separate check valve. Last one I did, the Reservoir ended up in an awkward place, so I wanted the check valve out where I could get at it for troubleshooting. We had a failure, and I felt smart when it turned out to be check valve and it was right out there easy to change.

The reservoir on the ‘75 MB300 is located on the inside of the passenger frame rail, under the passenger seat. It’s pretty easy to access. I’m feeling a little dumb, when it comes to understanding the concept of a one nipple reservoir. I know that the reservoir stores vacuum, but in order for it to do so it needs one nipple to draw the vacuum from the engine. How do you get the vacuum back to the part that needs it?

I’m a visual guy, so reading stuff sometimes doesn’t make sense to me. If anybody has a picture of the set up, using one fitting a check valve, that would be great to see.
