Where to find guidelines for building generator compartment?

[richard5933]

Any problems with this either restricting air flow or catching on things while driving?

Richard, I hadn't ever heard of or saw either!

I believe the flap underneath were factory installed.

The 3rd picture # 441 with the fan removed, what you see is the flap thru the hole.
It flops around just like a truck mud flap.

I made a deflector for my 12.5 power tech genny that is over sized in width and is like a wedge that sends the exhausted hot air towards the driver side of the coach . helped with the noise and got rid of the dust blowing around .

Quite simply get with Wrico to get sound deadening and use what they provided me-3/4" plywood with sound deandening-expensive though. Good Luck, TomC

Justin has been too busy to help me much with design of my generator compartment.  He did make a drawing of one possibility that I posted here.
I talked to Dick on Friday and emailed him pictures and dimensions.  He still hasn't called me back to give me advice about designing a generator compartment.

I finally decided to order just the generator and not order any sound deadening stuff with the generator.  Justin said it doesn't make sense to ship the plywood without a generator as the freight is really expensive.  There is a place that sells lead lined drywall and plywood locally so I will buy locally if I decide to go that route.

Sound deadening loud generators is old business. Do some research on the materials used in larger towed, portable generators. It is amazing how quiet some are when standing right next to them. They must have it all worked out to a science: intake, exhaust, vibrations, baffles, mufflers, etc.

BW, and Paso,
I don't know about factory installed ones an I suppose they could have been, but I have seen Thousands that had NO FLAPS compared to maybe a hundred that did. But maybe after something happens to the original one they just don't repair/replace most of them.
Or maybe it's northern thing were they have far more gravel roads, I don't know. I just know for a long time I'd never seen one period and one day I was at Bill's picking up some parts and noticed one and told him "Bill you better have your mechanic check that bus there's something hanging underneath it."
He looked and looked and finally asked where  so we walked over toward it and I pointed it out. He laughed and said "No I got those on all my buses, it cuts down on dust and debris from blowing everywhere."
I was curious so I got down on my knees an checked it out, an was impressed. I told him I was going to copy that and he told me to go ask his mechanic for an old one to use as a pattern. So I did and what he gave me was an old NAPA mudflap that was worn thin and ragged with 3/4" angle iron bolted on both ends with 3 holes drilled in each for a chain to hang it from.
I am sure his weren't factory, but they might have been at one time.
I do know for a fact they do help a lot!

There's only so much space under my bus (maybe 6" at best). How low do these flaps need to hang to not cause a reduction in air flow from the fan?

For that concern Richard, you could use a broom style.
