Diesel soot towed vehicle

I have a 2002 Fleetwood diesel pusher. It has the Cummings IBN300 engine.
My towed vehicle gets a lot of soot on the front.
The diesel runs fine and it gets good mileage.
Any ideas?

Clogged air filter, leaking injector would be my first check.

Yeah, I don't know what causes it but it shouldn't be there. We've never had any noticeable diesel soot on the front of out toad.

Best of luck.

Get a darker colored toad? ;^)

Not having any trouble here either - other than when I blew the turbo, which covered it with 19 qts of Syntec. That was fun cleaning up...

If you have a curved chrome exhaust pipe tip turn it so it faces about 45% out.

Hi, and Welcome to iRV2.
A Cummins of your vintage,stock, should not produce any noticible soot, as in other responces, check the air and fuel filters.Some add on chips can cause over fueling as can a leaking injector. So check the easy stuff first. Good Luck.

Used to pull a very heavy TT with a 2003 Dodge 3500 5.9TD, 4X4, DWR (truck and TT were white in color...5" aftermarket exhaust ended in a straight tip, flush with the fender). When towing in hills, soot would collect on the truck fender by the exhaust and the front of the TT. I never actually saw smoke and it only happened when pulling hard.

Assuming that you don't have a mechanical problem with the engine...I acquired a down turned exhaust tip to get the exhaust to go out and down away from the truck and trailer.

Easy fix for not much $$.
