Didn't have inside coach problems this winter - peppermint oil soaked cotton balls, mothballs and coyote urine soaked sand in small nylon stocking pouches plus aluminum flashing wall around each tire.
The buggers still found a way into the engine compartment tho. No debilitating damage but two nests built from engine insulation.
I'm gonna lift the rig on as many leveling blocks as I own this winter season and surround the entire chassis with a "mouse fence" of 12" aluminum flashing attached to 2x6's. If that doesn't work we'll store somewhere warm
