Dust from Gravel Roads in Bus

Hi FR Berk owners,
My first post. Bought a 2020 34QS this spring and love it!! The only thing that is a real nuisance (particularly for my wife) is the dust that comes in the bus when we travel down gravel roads. We live in a very rural part of Manitoba and it is 4 miles to pavement from where we live, not much choice in the matter. We have joined the seal on the front door which did help but the dust us still getting in. Any suggestions on where to start looking for leaks or is this something that we are going to have to live with it
Thanks,

I added automotive expanding sealant all around the outside of the step box, and any suspect places in the firewall as well as areas under and in the basement. I did it mostly for cold air, but it works for both.

Not just gaps in various body panels and undercarriage but also through storage compartment door seals.

You name it and it can be a source of dust. ESPECIALLY roof vents.

Thanks,

oh man!!! I love Manitoba!!!! No, not really, sorry.

It was a DUST nightmare on the crazy dusty road that led us into and out of the Angle Inlet(Minnesota, for those that don't know this 'crazy' section of the state, totally surrounded by Canada!), and 'Tom's Corner phone booth Border Patrol 'video' check in/out', and it engulfed our rig, too! It was a really annoying mess!

The reality is that the rear diesel and the 'build' of the RV on the chassis is what creates the ability for this 'very fine dust' to get brought up into the living areas. The turning of the engine and rear fan, the movement of the wheels on the dusty terrain, and the 'vacuum' that is sometimes created by the shear nature of 'driving'. There is probably not a SINGLE RV in this world that is 'dust proof', but yes, some are 'better' than others - a front engine gas motorhome would probably not complain about this 'problem'. CRAZY!!

Thanks,
Find an RV repair shop that has a Sealtech. It pressurizes the interior allowing the tech to locate leaks using soapy water or tracer elements.
This problem is why the Aussies run some of their off-road trailers down the road under positive pressure.

If you have a fantastic fan, or similar, you might try reversing the wires to make it blow air from the roof into the RV. It should help to pressurize the RV and hopefully keep most of the dust out.

is the dust in one area over the other? OR is it all over?

The dust is now worse at the back of the bus and at back of bathroom vanity , the entry door is better since we sealed gap in door molding. See attached pics prior to door seal repair

Is the vent fan and the window both closed in the bathroom? The fan vent should be able to get adjusted on the multiplex. Also the window closed all the way? I ask because these should be the only two potential entry points in the bathroom. Also in the rear of the coach is the dust in bedroom or in the rear storage area?

The bathroom fan vent and all windows were closed. The dust appears to be coming from under the vanity on right hand side and from under the bed.
