Inclement weather needs a little preparation. Thank God for weather radar apps. A couple things that we do to help keep reduce the "muddy" mess:
1. We use
this boot mat from Lowes. It can place outside on fair weather days and inside adjacent to the entry door when the sky is not so kind.
2. Plastic storage bins are wonderful for the fresh water hoses, even when they're muddy. They contain the dirt until we reach home. Then we can properly clean, dry, and store them. Our waste hoses and adapters are stored underneath the frame via a
custom fence post and gutter appendage. No real need to clean them more than a "rinse off" at the next camp site.
3. I carry a towel thats devoted to wiping off the power cord as it retracts into the interior of the coach. Pretty simple process.
4. If a threat of heavy rain is forecasted, the awning is retracted because "where there is rain, there is wind". If we do put away the awning wet, it is sure to be extended within the next day to dry out. One of the nicest upgrades we did to our coach was installing slide toppers. These help tremendously with debris and leaves, as much of it falls off as the slides are retracted in. We haven't had a problem with pine needles but we there have been times that a sticky twig doesnt fall of the topper. A broom face is used to sweep the slide topper as the DW retracts it slowly.
Hope this helps.
