thank you for ur time
Avenger, you could try getting yourself a "basket filter" from a residential furnace, cut it up to fit into the ducts below the grates.
Cut up enough to last the trip and change them every week.
I started doing this in our home 25 years ago and have used the. In trailer with great success.
