Here is a couple of shots of my genset door assembly...
Maybe the front door vent as a sealed intake for the genset, and the rear 2 with fans mounted for cooling.



I was thinking a couple of these mounted as puller fans... they are 12v and move 160cfm each.

Thankyou Sir!
I have been feeling like I was all talk and no action...
Gonna change that!

So, a trip to Home Depot provided some parts to map out the repair/upgrade.
This is what i have in mind...



So, then is was on to the Drawer...
I think the pics will speak for themselves...

I guess this post should be called "Anatomy of a Classic Airstream Drawer"!



Note, my lock has no latch....
Can I buy this part?


Lid removed


Here is a reason why they leak...
Not sure if this is original, but look at the sealant... instead of catching water that runs off the outside skin, and shedding it... it funnels it onto the ABS drawer top... which has cracks and leaks!


Different cracks on the other side..., but same sealant issue..


After removing the visible screws, there are more UNDER the sealant... its a beast to remove!


ABS top removed revealing the seal tape... with gaps!



ABS top is pretty good except a few cracks that I will fix and reinforce with MEK/ABS Slurry and fiberglass.




I will sleep well tonight... Getting Er Done!

The missing part is called a Lock Cam.

The same thing is used on vending machine and tool box locks.

Any locksmith will have a selection or Home Depot or Lowes will sell a lock with a variety of cams.

Thanks Paul, If I cant find one, a piece of Aluminum bar stock will work.

Seems like everyone who has a classic has leaky drawers Mike...

A close look at my drawers was needed as they are getting wet inside when it rains, and the M/H has not moved...
I think I figured it out...
The rain runs down the bodyside until it reaches the drawer joint.. then gravity and surface tension sucks it into the gap, where it runs down the inside of the skin...
Like the blue arrow I drew on the pic below... Then because the Caulk is flat or ever radiused the water runs onto the drawer top, and thru any cracks it finds!

I am planning to put thin layer of Caulk back on, and make it a hollow negative curve, that will allow the water to flow along the channel and off the end, like the red arrow..

Letting the Chemicals do some work today...
Left some rust killer do its job on the interior overnight...
And got the paintstripper working on the exterior...




After the second coat...


What I thought was interesting is that the drawer side is made from T6061 T6..


Looking better..

Not going to seal those drawers with a MEK/ABS mix?

Yes, thats the plan Mike....

I am off to Home Depot for a bit more pipe for the genset, then over to the Airstream to do a test fit...

Hi Key,

When you get around to acoustic insulation, check out a company called "Soundown". They specialize in marine applications, engine rooms on everything from fishing boats to super yachts. I used it on the engine cover of my 325, which weighs about 50 pounds at this point, but it sure has quieted that Cummins just beneath it. Also, I believe that most of the Prevost class mega-mohos use pneumatic mounts on their generators which pretty much eliminates any vibration issues. My rig came to me without a generator, so I'm always thinking about this issue, and where to go with it.
Finally, if you run into anything rusty, POR-15 has got to be one of the greatest paint solutions of all time.
Great photos, its a pleasure following your exploits. Keep up the good work.
I'd also like to nominate you to receive another rivet!!

Charly.

Thanks for the tip and the suggestion I get another Rivet... I feel like I got my Master status for doing very little, so I need to make up for that!

The plan for soundproofing the compartment is pretty well advanced, and I will be getting the materials from here, which is an hour drive from me..
: SOUNDPROOFING & More Soundproofing! Super Soundproofing Co.

I spent some time on the phone with a Tech there called Randy, and he was very helpful, and had great suggestions.
The basic plan is a layer of MLV(Mass Loaded Vinyl), stuck to all of the walls, floor and door. Then with that will have a layer of closed cell foam on the main compartment walls, and a layer of Aluminized sheet of some type to make it wipe clean and light reflective.
The exact materials and thicknesses are still unsure at this time, as I need to figure out some clearances based on the fact that the genset will be moving up maybe 1/2" with the slides added.
Randy also suggested as I am doing that I should "Decouple" the genset mounting plate from the mounting tray with "Isolated bolts".
My research on this is ongoing, but this is the type of mounting I have in mind..
McMaster-Carr

Once I have the Genset running, cleaned up and on its slides, I will have all the clearances dailed, and will go down and meet Randy with all the Dimensions to decide. I will take the Genset door with me, as that's the tricky part, and he says its critcal to how quiet it will be.

Whatsever I buy, I will get some extra material to reline the Doghouse too.
